If you are looking to put more cars on the track, and more butts in the stands, I would suggests taking a page out of the 1990 IMCA Modified Rule book. This is a class that has grown wildly over the years. They are no threat to Late model car counts (a sprint car version would be no threat to your full up sprints), and there is one in every garage in Iowa. The most effective rule: Engline claim. Run anything you want, but if asked, you sell it right then and there for $XXX, or lose the win, monies, and points for the night with a two race suspension. It keeps the rich guys at bay, car counts high, stands full. One other note about people in the stands. Folks like to watch someone they know race. A relative, or co-worker. Somebody local. Around here, the stands are packed full of people there to watch their buddy run a four cylinder POS. They come to see Joe run, and are exposed to dirt track racing for the first time. Many get hooked. You may not be a fan of junk on wheels, but promoters around here are. Full stands, full pits, full pockets. Like 'em or not, they are the best thing to happen to racing in these parts in decades. Perhaps if more local guys could afford a low-budget sprint car, it would work for us as well.

There's my $.02. I've been preaching it to deaf ears for years, so bash away.
