Among others I've been to is Paragon Speedway & saw the Kinsers run one night, Bob, Steve, and Mark, not sure if Sheldon was there but I was at Texas World Speedway,(College Station) in 1979 when Sheldon finished a career best 3rd in Champ Cars(as they were called then)& no doubt saw him in the Hoosier Hundred dirt Champ race at least once. I worked for Grant King & we ran Chuck Gurney( 14 career victories & Champ in 1989) he was qualified fast near front, so we thought we had a chance in the race until till he hit first turn fence on first lap, IIRC!
