What caught my attention were some of the comments left on the site related to the town's arbitrary and unconstitutional actions - if the allegation is accurate.
From Robert K. Dean:
Your first mistake was asking permission. It certainly is proper to invite elected officials to attend, seeking permission isn't. Pick your public owned site, don't restrict anyone's movement in the area, be polite but well spoken, invite the press, especially local TV stations. Have someone film the event and upload it to YouTube for the record. You aren't using public park facilities, so no permit is required; you and several of your friends are simply gathering to redress government's behavior. Robert Dean - Communications Director - Tidewater Libertarian Party.David M. Lindsey:
Under the provision of Art. 1 Sec. 12 of the CVA and the Dillon Rule how does Abingdon deny any form of the people peaceably to assemble, and to petition the government for the redress of grievances.Ruth Hersey:
If we will not be stepping on anyone's toes we would like to address this question with Abingdon's Leadership.
The Constitution of Virginia 
Article 1 Bill of Rights.
Section 12. Freedom of speech and of the press; right peaceably to assemble, and to petition. — That the freedoms of speech and of the press are among the great bulwarks of liberty, and can never be restrained except by despotic governments; that any citizen may freely speak, write, and publish his sentiments on all subjects, being responsible for the abuse of that right; that the General Assembly shall not pass any law abridging the freedom of speech or of the press, nor the right of the people peaceably to assemble, and to petition the government for the redress of grievances.
Va. Constitution V
Here's your permit ~I'm proud of you guys. Patriots all.
The First Amendment of the US Constitution
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
Now, about that denial of the right to assemble, I think it might be time to lawyer up.
