Sears Point Formula Atlantic auto race
Farther back in the Atlantics field, we see Steve Hartgraves (#90), Ron Householder (#16) and Phil Simon (#74), all in Marches of various vintages. Looking at this photo, I have to wonder if the track security was napping that day. It hardly seems prudent to allow a spectator to be this close to a wall at the edge of the track for a standing start.
