Seen USAC Sprints first ever appearance {I think} (with USAC Midgets) at Angell Park Speedway, Sun Prairie, WI, in 2001, Jack Hewitt won the Sprint feature.

A few pavement tracks:
Seen USAC sprints (with USAC Midgets) at South Boston Speedway, Va on October 13, 2001, winners were Tracy Hines (#19 GMS) sprints, Tony Stewart Midgets. Mike Bliss was in the Hoffman 69 and he crashed on his second qualifying lap, the car could not be repaired. Long way for the Hoffman's to go and not get to race!
