That's really cool, there is a informal car show every Saturday in a strip mall parking lot here in WV.
Normal evening is about 50 to 200+ cars.
There is no fee to get in, they kinda of reserve about 1/3 of the parking lot for just old cars.
There is plenty of parking for people just driving up in their daily drivers.
The cool thing is that there is a couple of great restaurants in the same strip mall.
The restaurants love the business and it is a family atmosphere.
Me and the the wife take a couple of cars / jeeps over a couple of times a month.
All it costs me is dinner for my family.
