As a fan that has a track 10 minutes away that I don't go to every week because I don't care for the racing (late models, mods, street stocks, etc.), for me it's the classes. Admission price doesn't and wouldn't keep me away. If there were sprint cars or midgets run weekly with other stock car classes interspersed to keep the lights on, I'd be there every week. If I lived near an Indiana track with weekly sprint or midget shows, i'd be there. Just not an option for me.

Down there in the south though, if you're having trouble getting people to the track, my guess would be people just don't know about it or have much interest? But I have no clue, just a guess. Didn't really think there was much interest for open wheel racing down there?
