Warren,
How many car shows do they have in your area? We just have one big one and several smaller ones. The big one in April is limited to 2,300 cars because of lack of parking space. They keep talking about extending it across the river, but so far nothing has happened. I actually enjoy the smaller ones up in the mountains as it is cooler and there isn't 40,000 people pushing around. I believe the largest entry list they have had was around 3,600 cars and they had to turn down all those after 2,300. That brought on the panic to find parking as they hate to lose all that money. I remember the first year, 1990, they had this show and they were hoping to get 100 cars to break even. I think they got about 150 that year.
