There is a cruise-in in a little town in Western Illinois called Knoxville. It runs from 4-7pm tomorrow (Sat 8/28). It gets bigger every year. Small town that closes down the downtown area and has a live band and activities as well as food vendors and such. You should also check out the Maple City Cruise Night in Monmouth Illinois each year on the Friday before the first Saturday in August. It has 2,000 cars and attendance that triples the size of the town of 10,000.
