Be careful what you try guys. Rules are a must. many years ago a bunch of guys ran dirt sprints on pavement. Had a ball. Then a few pavement guys showed up with special cars. Then guys sold their dirt cars. Prices skyrocketed and the fun left. Gradually the originals disappeared. USAC, HOSS shows this.
Midgets did the same thing.
600 sidwinders did it too.
A couple guys got hurt and 2 special built cars did it in.
