What would you say is the “Knoxville nationals” of non wing racing? As in their biggest, highest paying race of the year. Kokomo Smackdown Turkey Grand Prix or other?

For me 4 Crown at Eldora however not highest paying.

Best attended USAC show? Let's Race Two with the WoO.

Highest paying? Smackdown $30,000 this year

Actual crown jewel for them is Indiana Sprint Week
