Billy Foster was making a name for himself in USAC, in both the champ cars and stock cars. He had a ride for the 1967 Riverside NASCAR race and had qualified for it when, during a practice run, his brake drum had a failure and he crashed, losing his life January 20th.
Gary Kershaw came down for the opening race to the NASCAR Grand National race in 1971 and surprised everyone, except himself and those who were aware of his skill. Kershaw went on to win numerous races in the Pacific northwest.
