Another great example of this was Illiana Speedway in Schererville Indiana. I was there for what turned out to be it's last race, The Bettenhausen, a few years ago.

They had a decent car count, probably more than 30 and I hung around the pit until the feature was getting ready to roll out. When I saw the grandstand, I was shocked! It was virtually empty.

The following Saturday, I happened to be driving by Illiana and traffic was backed up on Route 30 both east and west and the parking lot, which is very large, was practicably full!.
There was a demolition derby and school bus race going on. UNBELIEVABLE!!!
