Hi Kerry,

"Just a little memory jogging, USAC was the old Indy car league, CART broke off in a dispute with USAC, now history repeats itself with IRL breaking off in a dispute with CART."

USAC was the umbrella organization that covered Indy Cars, as well as USAC sprint and midget cars. USAC still is the umbrella organization for their sprint and midget car series. These series are still where most of the new talent moving into IRL rides learn how to drive a race car.
