Do you get the USAC sprints or the winged World of Outlaws tour?
Dirt track racing is absolutely better than asphalt tracks.
My local (2+ hours away) dirt track ran a special show last Saturday night, and let the modifieds and late models run any engine they wanted and any body configuration, including wings and sideboards. Some guys were running alcohol injected engines, monster wings, all kinds of cool stuff.
They call that run what ya brung. Where I watch the dirt racers it's usually world of outlaws but there are several tracks inside of an hour from me.
