We have a few small tracks like this. There is a drag strip less than an hour from here. I also just found another oval track, except it is cement instead of dirt. I am definitely going to try to hit that other track soon, the same types of cars. I hate that all of the good autocross tracks are no less than 3-4 hours from us. I want to see cars that I actually recognized going crazy.
I think demolition derby would be so fun to watch, haven't seen it before. I did go to the monster trucks once as a kid. Now that I am thinking of it, dirt bikes and some motorcycle races would be fun too. I love pretty much anything that screams and goes fast, most importantly that requires a lot of skill.
