I have a few things for you to think about on this one. First and foremost I believe USAC wants to have pavement sprintcars! BUT, as a promoter would you have an event that attracted very few people? I was a paying customer along with the other 100 people at IRP this year. Racetracks have to want them, cars have to go race, people have to pay to watch! These three things are what makes the dirt sprint car races work- end of story.
