Gary Davis got his start as the stuntman for "Evel Knievel." Yeah, it's like being Chuck Norris' bodyguard. CBS hired the youngster to do wheelies and jump over exploding cars for their pilot episode, starring Sam Elliott as the King of Daredevils. Now Evel Knievel Museum founder Lathan McKay shares some home videos that the Castine family captured way back in 1974 at Beeline Raceway, where the television pitch was filmed.
