I hear ya. At one time, there were four ovals and one drag strip all within a 20 minute drive of my house. They are all goen now and the closest one is almost an hour away.
On the plus side, there are plans going together to build three new road tracks in the region. Unfortuntly, they are all pretty far away in travel time.
I'm not sure when or why things changed, but they did. Developers grubbing for money, neighbors who didn't want them around, transplants who don't like them, high insurance rrequirements, a population willing to sue at the drop of a hat. I don't know what caused it exactly, but probabaly a combination of all of the above.
