and what did Chet do to grow the sport other than act like a straight up hill billy?

What Chad and Kyle are doing is dragging the sport into money, thru organization. USAC is the organization, and sometimes I think it must still be 1965. The caste system they had worked for a long time. Changing taste and technology put paid most of their races and most of that was the Club's inability to change.

It even cost them the Indy 500

PS - I'm not on social media. Tik Tok:-) to bad our society puts so much weight into meaningless, worthless information. Jesus, life goes off in front of you. Get off your phone. I long for the day the phone was on the wall in the kitchen. Most idiots could not leave the house without a phone.
