Hometown 80's car show?

["_designer_" <_designer_@xxxx>]

I want to create a local 80's theme car show (and hopefully get the 
DeLoreans in my area to attend, too). I'd like it to be all legal. 
Do any list members have experience with this? Do I need permits? 
Any help would be greatly appreciated!

Sincerely,
Tom M :)
