The Market Street Commandos was a motorcycle club that, in 1947, along with the Boozefighters and the Pissed Off Bastards of Bloomington, participated in the highly publicized Hollister incident (later immortalized on film as The Wild One ). In 1954 the Fontana Hells Angels merged with the Market Street Commandos to become the San Francisco chapter of the Hells Angels.
