By me, my town of Downers Grove, IL has a car show every Friday all summer long. The village does allow street signs put up each morning of the show to alert folks not to park on Main St. and in one other commuter lot. It usually draws about 150 antiques with some late model hot cars as well. Way over 200 cars on the best nights btw.
Most of the guys are pretty handy with tools and the like yet many of the cars only come out for the shows, many of which are held on different nights in 'burb's within 20 miles. Heck, one could see cars every night of every week except Sunday and not have to drive far to do so. Lemont, Glen Ellyn, Berwyn, Naperville and more all have shows coordinated by about 5-7 big area car clubs.
Fun to watch but I don't show either of my Stangs. Way, way too boring to sit in a folding chair for hours on end and get mainly kids asking questions. Me, I'd rather go for a long drive with the windows down, the engine growling and the wind in my hair!
