*645OPINION OF THE COURT
ADAMS, Circuit Judge.These cases arise from the efforts of the United States Postal Service to bar potentially disruptive charitable solicitation on its property, efforts which frustrated an attempt by political activists to solicit financial contributions near the doorways of two local post offices. The United States Magistrate found the four defendants guilty of soliciting and depositing literature in violation of applicable Postal Service regulations. Relying in part on the First Amendment, the district court vacated all the convictions. Because we differ with the district court’s constitutional analysis, we will reverse and remand the matter in order that a portion of the magistrate’s judgment may be reinstated.
I.
The four defendants — Mitchell Bjerke, Constance Brown, Martha Zoller, and Margaret Scott — are affiliated with the National Democratic Policy Committee. That organization is closely associated with Lyndon H. LaRouche, Jr., an independent candidate for President on several state ballots in the 1984 general election.
Beginning in the early summer of 1984, defendants engaged in political activities outside a number of post offices in the Pittsburgh area. Their usual practice was to set up a card table near a post office entrance, and then to encourage those using the post office facilities to purchase political literature displayed on the table.
At three post offices — McKnight, Monroeville, and Mars — defendants were issued citations and charged with depositing nongovernmental literature on postal premises, in violation of 39 C.F.R. § 232.1(o) (1985), and soliciting contributions on such property, a violation of 39 C.F.R. § 232.1(h)(1) (1985). Following conviction before the magistrate on all counts, the district court vacated the convictions, ruling that there was insufficient evidence to support the charges of depositing literature, and that the convictions of Bjerke and Brown for soliciting abridged their First Amendment rights.
The solicitation charges against Bjerke and Brown, the subject of this appeal by the government, are based upon three incidents: On November 16, 1984, Brown was observed at a card table set up on a walkway four to five feet from the entrance of the McKnight post office in Pittsburgh, attempting to solicit contributions; on December 12, 1984, Bjerke engaged in similar activity on a grassy area a little farther from the entrance; and on November 29, 1984 both Bjerke and Brown were seen at a table set up on a walkway one foot from the entrance of the post office in Monroe-ville, Pennsylvania. For these incidents, the magistrate imposed fines and assessments totalling $100 each on Bjerke and Brown.
There is no evidence that defendants at any time blocked access to the buildings. Nor is there any showing that defendants’ activities caused any disturbance at the Monroeville facility. However, there is considerable evidence that the operations at the McKnight post office were affected by the solicitors.
Both the McKnight branch manager and another postal official testified that over a six-month period numerous customers of the post office complained about the solicitations, causing window clerks and the managers themselves to spend a significant amount of time placating irate patrons. Twenty customers added their names to a list of complainants maintained by clerks, until the branch manager ended the practice of keeping a list of complaints. In addition, the McKnight manager stated, regular bulk mailers began arriving late in the day in order to avoid the activists, requiring the post office to stay open as much as a half-hour beyond its regular closing time.
The United States has filed a timely appeal, contesting only that portion of the district court’s ruling holding that Bjerke and Brown’s convictions for soliciting violate the First Amendment.
*646II.
A preliminary question is whether this Court has jurisdiction to review the district court’s decision favoring the defendants. The prosecution asserts that our jurisdiction rests on 18 U.S.C. § 3731 (1982). That statute reads, in relevant part:
In a criminal case an appeal by the United States shall lie to a court of appeals from a decision, judgment, or order of a district court dismissing an indictment or information or granting a new trial after verdict or judgment, as to any one or more counts, except that no appeal shall lie where the double jeopardy clause of the United States Constitution prohibits further prosecution.
Defendants argue first that because this prosecution for petty offenses was initiated by citations, and not an indictment or information, the statute is inapplicable. But in United States v. Wilson, 420 U.S. 332, 337, 95 S.Ct. 1013, 1018, 43 L.Ed.2d 232 (1975), the Supreme Court held that § 3731 is designed to remove all barriers to appeals by the government in criminal cases, and to permit such appeals wherever the Constitution so allows. In addition, the statute itself states: “The provisions of this section shall be liberally construed to effectuate its purposes.” Accordingly, it is reasonable to permit an appeal even where the case involves a petty offense. United States v. Moore, 586 F.2d 1029, 1031 (4th Cir.1978) (violation notice for petty offense is “functional equivalent” of indictment or information); see also United States v. Lee, 786 F.2d 951, 956 (9th Cir.1986).
The relief sought by the United States is also within the contemplation of the statute. After the district court’s decision, the only course available to the magistrate is dismissal of the citations on which the charges are based. Section 3731 permits the government to appeal under these circumstances. See United States v. Beck, 483 F.2d 203, 206 (3d Cir.1973) (looking to the “practical effect” of the district court’s decision), cert. denied, 414 U.S. 1132, 94 S.Ct. 873, 38 L.Ed.2d 757 (1974).
Further, double jeopardy presents no bar to this Court’s review of the district court’s order vacating convictions entered by a magistrate. The double jeopardy clause is implicated only where there is a threat of multiple punishments or a second prosecution. Wilson, 420 U.S. at 344, 95 S.Ct. at 1022. Such is not the case where, as here, the appellate court is asked only to reinstate a vacated verdict. Id. at 345, 95 S.Ct. at 1022.
Therefore, we hold that § 3731 provides this Court with jurisdiction over the present appeal by the government, and there is no constitutional bar to such an appeal. Other courts of appeals have reached the same conclusion in cases involving district court reversals of convictions entered by magistrates. United States v. Forcellati, 610 F.2d 25, 29-30 (1st Cir.1979), cert. denied, 445 U.S. 944, 100 S.Ct. 1342, 63 L.Ed.2d 778 (1980); Moore, supra.
III.
Our analysis of the merits begins with the applicable Postal Service regulation. It states:
Soliciting alms and contributions, campaigning for election to any public office, collecting private debts, commercial soliciting and vending, and displaying or distributing commercial advertising on postal premises are prohibited.
39 C.F.R. § 232.1(h)(1) (1985). As the government concedes, the rule does not prohibit the distribution of literature or the discussion of public affairs on post office property.1
The government further concedes that solicitation activities are expressive speech within the protection of the First Amendment. “[S’Jolicitation is characteristically intertwined with informative and perhaps *647persuasive speech seeking support for particular causes or for particular views on economic, political, or social issues, and ... without such solicitation the flow of such information and advocacy would, likely cease.” Village of Schaumburg v. Citizens for a Better Environment, 444 U.S. 620, 632, 100 S.Ct. 826, 833, 63 L.Ed.2d 73 (1980). See also Cornelius v. NAACP Legal Defense and Educational Fund, Inc., — U.S. —, 105 S.Ct. 3439, 3447, 87 L.Ed.2d 567 (1985).
Nonetheless, the United States contends that the content-neutral prohibition of financial solicitation on postal premises is a constitutionally valid exercise of control over its property.
A.
In a long line of cases, the Supreme Court has made clear that the government, “no less than a private owner of property, has power to preserve the property under its control for the use to which it is lawfully dedicated.” Adderley v. Florida, 385 U.S. 39, 47, 87 S.Ct. 242, 247, 17 L.Ed.2d 149 (1966) (upholding trespass conviction arising out of demonstration held on the nonpublic grounds of a county jail). Thus, whether the government must permit access to public property for expressive activities depends on the nature of that property-
The Supreme Court recently set forth the appropriate analysis for resolving claims of access to public property in Cornelius v. NAACP Legal Defense and Educational Fund, Inc., — U.S. —, 105 S.Ct. 3439, 87 L.Ed.2d 567 (1985). If the public property to which individuals seek access is a traditional public forum such as a street or park, the Court explained, any exclusion must be based on a compelling state interest, narrowly tailored to promote that interest. A time, place or manner restriction is also permitted if it is content-neutral, and if it is designed to advance a significant governmental interest. Id., 105 S.Ct. at 3448. The same rules apply to a nontraditional forum that is designated by the government as a public forum, id., but officials may choose to close such a designated public forum at any time. Perry Education Association v. Perry Local Educators’ Association, 460 U.S. 37, 46, 103 S.Ct. 948, 955, 74 L.Ed.2d 794 (1983). However, restrictions on access to government property that generally has not been open for public expression, characterized by the Supreme Court as a “nonpublic forum,” need be only reasonable and content-neutral. Cornelius, 105 S.Ct. at 3448.
Defendants were charged with conducting activities on or near walkways located on postal premises. We must therefore consider the Supreme Court’s decision in United States v. Grace, 461 U.S. 171, 103 S.Ct. 1702, 75 L.Ed.2d 736 (1983). In Grace, the Court held that a public sidewalk surrounding the Supreme Court building is a public forum, even though included in a statutory description of Court property on which certain expressive activity was forbidden. Id. at 179, 103 S.Ct. at 1708. But Grace does not stand for the proposition that any outdoor path is a traditional public forum.
In Grace, the Court focused on a sidewalk bordering streets that appeared identical to the public sidewalks found in every urban area. As the Court observed regarding the area at issue, “[t]here is no separation, no fence, and no indication whatever to persons stepping from the street to the curb and sidewalks that serve as the perimeter of the Court grounds that they have entered some special type of enclave.” Id. In contrast, the Grace Court distinguished Greer v. Spock, 424 U.S. 828, 96 S.Ct. 1211, 47 L.Ed.2d 505 (1976), which held that streets and sidewalks of a military reservation open to the public only on a limited basis constitute a nonpublic forum. In Greer, even though civilians were freely permitted to visit unrestricted areas, signs were posted at the reservation entrances barring solicitors and warning of possible vehicle searches, thus making it clear to persons approaching that they were departing from public thoroughfares. Id. at 830, 96 S.Ct. at 1213. See also Student Coalition for Peace v. Lower *648Merion School District Board of School Directors, 776 F.2d 431 (3d Cir.1985) (school athletic field that was fenced but unlocked did not become a public forum simply because it was used for park-like activities).
The dissent suggests that Greer’s finding of a nonpublic forum is based not on the Supreme Court’s view of “the lay of the land,” but instead on military necessities. Post at 654. This position, however, fails to consider the effect of Flower v. United States, 407 U.S. 197, 92 S.Ct. 1842, 32 L.Ed.2d 653 (1972) (per curiam), in which the Court held that the streets of a military reservation were a public forum where officials had “abandoned any claim of special interest in regulating” expressive activity. Greer, 424 U.S. at 837, 96 S.Ct. at 1217. Thus, the Greer-Flower distinction illustrates the point that where the walkway is clearly within the perimeters of government property — as opposed to the situation in Grace — the government may choose to restrict the use of the walkway and limit public expression at that location.
B.
A multitude of different layouts and geographical configurations characterize the thousands of post offices in the United States. Undoubtedly, some of these facilities include exterior walkways that, although nominally within federal property, are indistinguishable from public sidewalks. In those situations, Grace suggests that those paths be considered public forums.
Defendants contend that because the regulatory ban on solicitation present in this case applies indiscriminately to all outdoor walkways, including those indistinguishable from sidewalks, it is overbroad and an invalid restraint on First Amendment rights. But this-proposition is not as clear as defendants suggest. A statute or regulation that is broadly applicable to public forum property is not per se infirm; as noted, such a proscription may be justified by a sufficient governmental concern. In any event, the case at hand does not provide the proper occasion for an overbreadth challenge. It is true that one may question an overbroad provision even if a properly limited ordinance could validly apply to his own conduct. But in order to make such a challenge the overbreadth must be “substantial.” Broadrick v. Oklahoma, 413 U.S. 601, 615, 93 S.Ct; 2908, 2917, 37 L.Ed.2d 830 (1973). “[T]he mere fact that one can conceive of some impermissible applications of a statute is not sufficient to render it susceptible to an overbreadth challenge.” Members of the City Council v. Taxpayers for Vincent, 466 U.S. 789, 800, 104 S.Ct. 2118, 2126, 80 L.Ed.2d 772 (1984).
Here, defendants made no showing concerning the physical layout of any post offices other than those at which they engaged in soliciting. Thus, on this record, we are unable to determine whether the regulation at issue is substantially over-broad in its application to outdoor walkways.
As defendants have failed to assert a sufficient challenge to the regulation based on its alleged overbreadth, we decline to resolve whether the regulation may apply to exterior walkways that are indistinguishable from public sidewalks, like those in Grace. Instead, we turn to the question whether defendants’ particular activities at the McKnight and Monroeville post offices were properly subject to regulation. We conclude that the provision as applied to these activities does not offend the Constitution.
C.
The particular areas used by defendants for solicitation are nontraditional public forums. At the McKnight and Monroeville post offices, the two facilities involved in this appeal, the entrance areas are set well back from public thoroughfares. At both locations, an exterior walkway abuts the post office building, and a parking lot, also on postal premises, separates that walkway from the street. At Monroeville, a walkway connects the path in front of the building with the street, but *649the former walkway does not lead directly to the post office entrance where defendants conducted their affairs. The factual situation in this case is thus more analogous to the sidewalks in the military reservation in Greer than to the public sidewalk in Grace; the walkways are not traditional public forums, since any person who has crossed the McKnight or Monroeville parking lot and stepped onto a walkway adjacent to the post office has entered an enclave separated from the public thoroughfare. The government is permitted to maintain such nonpublic enclaves.
It is clear that the walkways at issue here, bordering free-standing buildings a good distance removed from the street, could not be confused with municipal sidewalks. There is no evidence in the record that contradicts this. Thus, this case is not similar to Grace, in which public sidewalks became nonpublic only by congressional edict. Here, the Postal Service has constructed and maintained walkways well inside the perimeters of its own property. Contrary to the dissent’s suggestion, we believe it is of no moment that the McKnight and Monroeville walkways are the only avenues available for customers wishing to enter those post offices. As the Supreme Court cases since Adderley indicate, the government may restrict the use of its property and dedicate it as a nontraditional forum; it need not open for public discourse property dedicated to other purposes, even if that property would provide a useful arena for those wishing to express their views.
The walkways in question were not dedicated to serve the traditional functions of streets or parks, but rather for the particular function of accommodating post office patrons on official business, unlike the urban sidewalks in Greer. Indeed, it can hardly be doubted that the function of Postal Service property is to facilitate the provision of efficient postal services, and not to provide a public platform for political advocacy. See 39 U.S.C. § 101(a) (1982).
At bottom, this is a simple case in which the Postal Service, as owner of the property in question, has barred certain activities immediately adjacent to post office entrances. The Supreme Court has directed repeatedly and emphatically that governments must be permitted reasonable control over such nontraditional public forums. See, e.g., Cornelius, 105 S.Ct. at 3448; Perry, 460 U.S. at 46, 103 S.Ct. at 955; United States Postal Service v. Council of Greenburgh Civic Associations, 453 U.S. 114, 129-30, 101 S.Ct. 2676, 2685, 69 L.Ed.2d 517 (1981); Greer, 424 U.S. at 836, 96 S.Ct. at 1216; Lehman v. City of Shaker Heights, 418 U.S. 298, 302-03, 94 S.Ct. 2714, 2716-17, 41 L.Ed.2d 770 (1974); Adderley, 385 U.S. at 47, 87 S.Ct. at 247.
Defendants also argue that the Postal Service has effectively created public forums outside McKnight and Monroeville as a result of certain practices. They note that no regulation bars public speaking or the distribution of literature outside post offices, and that newspaper vending machines and a gumball machine encouraging charitable contributions were found at postal facilities in the area.
However, that the government permits selective access to a nontraditional forum does not manifest an intent to designate an area a public forum for all expressive purposes. In Cornelius, for example, a charitable fund-raising drive conducted by federal employees allowed the participation of 237 voluntary agencies, but excluded legal defense and political advocacy groups which desired to participate. The Supreme Court held that this limited access to a nonpublic forum did not create a public forum. 105 S.Ct. at 3450. Similarly, in Perry, a school district permitted use of internal mailboxes by the teachers’ elected labor representative, as well as by civic and church groups such as the YMCA and Cub Scouts, but denied access to a rival teachers’ union. The Court held: “This type of selective access does not transform government property into a public forum.” 460 U.S. at 47, 103 S.Ct. at 956.
*650The post office entrances in question here were nonpublic areas, and there is no evidence of any official intent to designate these areas as forums for unlimited public expression. Accordingly, we must analyze the Postal Service’s ban on solicitation outside McKnight and Monroeville in accord with the appropriate constitutional standards for nonpublic forums.
D.
As stated earlier, a regulation of expression on government property that is a nonpublic forum will be sustained if it is reasonable, and does not discriminate on the basis of content. The provision at issue meets these tests as applied to the areas immediately adjacent to the McKnight and Monroeville post office entrances, where defendants were cited for their actions.
The federal bar on solicitation on postal premises is content-neutral. It does not discriminate on the basis of the speaker’s message, nor does it preclude all expression regarding any particular topic. See Consolidated Edison Co. of New York, Inc. v. Public Service Commission, 447 U.S. 530, 537, 100 S.Ct. 2326, 2333, 65 L.Ed.2d 319 (1980). Rather, it merely deprives the speaker of one means of expression found disruptive by Postal Service officials.
According to these officials, solicitation activities are especially likely to interfere with their mission to provide reliable postal services. Before 1978, the Postal Service allowed solicitation in post office lobbies by designated charitable organizations. It then determined that this practice was unsatisfactory, since it caused crowding of needed lobby space, and required employees to apportion the scarce area. See 43 Fed.Reg. 38824 (1978). As a result, the regulation at issue here was promulgated.
In the present case the district court determined that the record demonstrates that the regulation is necessary as to post office interiors, but that there is no evidence that similar measures are required for exterior areas. We do not agree. The evidence of disruptions at McKnight demonstrates the reasonableness of the regulation as applied to the entrance area of that post office, and although no evidence was introduced concerning the impact of solicitation in an identical area outside Monroe-ville, officials could reasonably expect similar effects. “[T]he government need not wait until havoc is wreaked to restrict access to a nonpublic forum____ The First Amendment does not forbid a viewpoint-neutral exclusion of speakers who would disrupt a nonpublic forum and hinder its effectiveness for its intended purpose.” Cornelius, 105 S.Ct. at 3453-54.
It is of consequence that defendants placed the tables that they used for solicitation purposes within ten feet of the McKnight entrance, and barely one foot from the front door of the Monroeville post office. At such proximity to the entrances, the likelihood of disrupting traffic and disturbing patrons is great, and postal officials were certainly reasonable to act in response.
The district court further observed that the regulation cannot achieve its purpose of preventing disturbances at post offices if it is applied only to exterior walkways within postal premises but not, pursuant to Grace, to municipal sidewalks, some of which are immediately outside some post offices. But authorities need not be consistent in their treatment of public and nonpublic areas, and the only question here is whether the regulation of the nonpublic forum reasonably advances the governmental interest. In this case, it clearly does. Moreover, the fact that alternative areas are nearby and available for communication, rather than condemning the regulation, enhances its reasonableness. Not only may defendants engage in solicitation outside postal premises, but they may participate in a wide range of expressive activities on the federal property itself. Significantly, no regulation prevents defendants from distributing literature on the post office property; and such literature may provide the organization’s address to persons *651who may wish to send contributions to the political cause.
Our decision today does not resolve whether solicitation is permissible on postal premises that are at a greater distance away from the entrances to the buildings than is the case here. At both McKnight and Monroeville, walkways appear to be present up to 30 feet from the entrances, and still next to the parking area. Arguably, the Postal Service’s restrictions may not be reasonable as applied to walkway locations that are at a great distance from the entrances. It is quite possible that following judicial resolution of various disputes involving the present regulation, the rule will operate no differently from that sustained in Heffron v. International Society for Krishna Consciousness, 452 U.S. 640, 101 S.Ct. 2559, 69 L.Ed.2d 298 (1981). There, the Supreme Court upheld a state fair rule which, in order to assure the safe and orderly flow of traffic, barred solicitation as well as distribution of literature in public aisles and limited such activities to a specified booth. As here, the rule in question permitted unencumbered discussion at any place within the public premises.2
That the Postal Service singled out solicitation for regulation is also reasonable. It determined: “The solicitation of alms and contributions is an inherently more aggressive form of conduct, and more likely to hinder the orderly transaction of postal business, than is the expression of ideas.” 43 Fed.Reg. 38824 (1978). Face-to-face solicitation for money is more likely to be a greater obstacle to the flow of traffic. See, e.g., Heffron, 452 U.S. at 665, 101 S.Ct. at 2573 (1981) (Blackmun, J., concurring in part and dissenting in part). Where, as in this matter, the solicitation occurs at the entrance to a post office, it is more likely to delay and harass patrons intent on conducting their postal affairs. “Although the avoidance of controversy is not a valid ground for restricting speech in a public forum; a nonpublic forum by definition is not dedicated to general debate or the free exchange of ideas.” Cornelius, 105 S.Ct. at 3454.
In Perry, the Supreme Court permitted the exclusion of the rival union from access to a nonpublic mail system, in order to preserve “labor peace” in the school district. 460 U.S. at 52, 103 S.Ct. at 959. A similar goal, achieving peace in the federal workplace, justified exclusion of controversial groups from a fund-raising campaign. Cornelius, 105 S.Ct. at 3453. The Postal Service was equally reasonable in banning controversial solicitation practices in the areas that are nonpublic forums immediately outside post offices.
Therefore, as applied in this case the regulation withstands First Amendment scrutiny. The entrance areas at issue are nonpublic forums, in which the Postal Service rule advances reasonable and neutral purposes.
E.
Our approach differs in some respects from that employed by the Court of Appeals for the Seventh Circuit in a similar case. While we do not necessarily disagree with all the views expressed by that Court, we do not find it necessary at this time to follow its analysis. Ours is a narrow decision resolving the propriety of the regulation only as applied to nonpublic forum areas directly outside the McKnight and Monroeville post office entrances.
In National Anti-Drug Coalition v. Bolger, 737 F.2d 717 (7th Cir.1984), a group seeking to sell literature challenged the solicitation regulation on its face, and also as applied to those wishing to set up card tables on “ingress/egress” walkways outside post offices in a federal judicial district *652in Illinois. The appellate court stated that there was insufficient evidence of the configurations of all post offices in the district on which to determine whether to treat the walkways as public or nonpublic forums. But, the panel majority held that, even assuming all walkways were public forums, the regulation was a valid time, place or manner restriction.
First, the court reasoned that the Postal Service’s interest in providing prompt, reliable, and efficient service is a significant one, and is properly advanced by the regulation. Such an interest justifies a content-neutral time, place or manner restriction. Second, the majority held that the rule did not sweep too broadly in its application to any post office, citing the Supreme Court’s decision in United States Postal Service v. Council of Greenburgh Civic Associations, 453 U.S. 114, 101 S.Ct. 2676, 69 L.Ed.2d 517 (1981).
In Greenburgh, the Court upheld against constitutional attack a statute prohibiting the private deposit of mailable matter in Postal Service-approved letterboxes. The Court declared that such receptacles, situated in front of millions of homes, are nonpublic forums, and may properly be the subject of broad regulation. In fact, the opinion states, Congress and the Postal Service “must obviously adopt regulations of general character having uniform applicability throughout the more than three million square miles which the United States embraces. In so doing, the Postal Service’s authority to impose regulations cannot be made to depend on all of the variations of climate, population, density, and other factors that may vary significantly within a distance of less than 100 miles.” Id. at 133, 101 S.Ct. at 2687.
The Seventh Circuit held that similar considerations permit broad regulations of the time, place, or manner of expressive activities in a presumably public forum, that is, the outdoor walkways. But Greenburgh concerned nonpublic forums, in which “[t]he Government’s decision to restrict access ... need only be reasonable; it need not be the most reasonable or the only reasonable limitation.” Cornelius, 105 S.Ct. at 3453 (emphasis in original). The National Anti-Drug Coalition reasoning may well be correct, but then again it may be that in the context of a public forum the Postal Service’s interest in uniform regulation should give way to the normal presumption that regulation of First Amendment activity must be specific and narrowly tailored. See NAACP v. Button, 371 U.S. 415, 438, 83 S.Ct. 328, 340, 9 L.Ed.2d 405 (1963) (“Broad prophylactic rules in the area of free expression are suspect____ Precision of regulation must be the touchstone in an area so closely touching our most precious freedoms.”).
In the present matter, involving the reasonable application of a rule to activity in a nontraditional public forum, we need not reach further to decide whether such a rule could, consistent with the First Amendment, apply to property that is a public forum pursuant to the rule of Grace. Therefore, we do not follow at this time the approach employed in National Anti-Drug Coalition.3
IV.
In summary, defendants may publicly express their views while on postal property, they may distribute political literature, and engage patrons in any lawful dialogue. In fact, they may even solicit financial contributions immediately outside postal premises, and perhaps even on certain portions of postal property. They are simply required not to engage in solicitation at a place *653where such activities would obstruct necessary and nonpolitical post office operations.
We therefore conclude that the solicitation regulation at issue here is reasonable as applied, in a neutral fashion, to certain nontraditional public forum areas immediately outside the entrances to the McKnight and Monroeville post offices, but on post office property, where defendants engaged in soliciting funds. Thus, the district court erred in vacating defendants’ convictions for violating this regulation. Its order will be reversed, and the case will be remanded with instructions to reinstate the judgment of the magistrate with respect to the solicitation charges against defendants Bjerke and Brown.
. The district court vacated defendants’ convictions under § 232.1(o), which prohibits “depositing or posting handbills” on postal premises. holding that this regulation does not bar the mere distribution of literature. The prosecution now agrees, and does not contest this ruling.
. In International Society for Krishna Consciousness, Inc. v. New Jersey Sports and Exposition Authority, 691 F.2d 155, 163 (3d Cir.1982), in a statement sur denial of a petition for rehearing, I questioned the panel’s application of public forum analysis to a race track and stadium, modern centers for public gatherings. But that case is not applicable here. The decision there upheld a ban on distribution of literature and solicitation applied to an entire sports complex. The present matter involves a restriction only on solicitation, and on that specific means of expression only in a small area of the public premises.
. In another recent case, American Postal Workers Union v. United States Postal Service, 764 F.2d 858, 861 (D.C.Cir.1985), cert. denied, — U.S. —, 106 St.Ct. 792, 88 L.Ed.2d 770 (1986), the court, addressing a regulation limiting voter registration practices on postal premises, held that all those premises are nonpublic forums. The decision did not refer to Grace, and thus leaves questions as to whether the District of Columbia Circuit’s opinion should be interpreted broadly. It appears that all the practices before the court in American Postal Workers involved activities within post office buildings, in areas that tire almost certainly nonpublic forums. See 595 F.Supp. 1352, 1354 n. 3 (D.D.C.1984) (district court opinion).
