You’re not going to be able to plop a big time USAC race in an area that doesn’t have a history with non-winged racing.

The places where I think it could work are Indiana (obviously), Eldora, Knoxville (given the history of non-winged racing), Arizona and California. Central Pa could also make it happen.

If I were USAC, I’d create a new triple crown where Kokomo Smackdown and the Sprint car portion of the 4 crown each paid $25k to win, and you rotated the 3rd event to Knoxville, Williams Grove and some other historic track.
