Unser crashed out of the 1968 race. His brother Bobby won, and incidentally joined the 100 mph Club for himself. Al Unser missed the 1969 race due to a broken leg suffered in a motorcycle crash earlier in the month. In 1970, he came back to win the race in dominating fashion. His average speed of 155.749 mph was well over the requirement to be invited into the club, and he was expected by all to be honored as the next member. However, after McGeorge's retirement, and subsequent passing, the 1971 banquet never happened. The club was quietly abandoned and membership was closed without Al Unser ever being officially inducted.
