Man, it looks like these guys had fun. Can anyone even imagine a weekend enduro of ripping around the San Francisco area on these open piped beasts? You'd get fined thousands of dollars and get chucked in jail for even letting your tires touch the beach these days. Modern Society is a drag! Look at the face on Charles Miller as he wheelies up a sand hill with the ocean in the background. Classic. The San Francisco Motorcycle Club still exists. A guy that I built a Preunit Triumph Chopper for in the late 1990's became a member. I'd love to visit the clubhouse and take in some history.
