No chance of a dirt race the weekend of The 500. The Carb Day and Legends Day concerts definitely would preempt any racing... and the musical acts draw many more customers than they could even fit around the dirt track. Now, could they put on a race during qualiying weekend? Possibly. It could work.

The World of Oulaws want to race there. Badly. Although I think it's more likely to see them there on a standalone event, eventually.
