 Filmed at Spahns Movie Ranch near Chatsworth, CA, in late 1968. The  ranch was used for occasional filming of TV westerns like  _"Bonanza" (1959)_ (qv) and _"Lone Ranger, The" (1949)_ (qv), as  well as for David O. Selznick (qv)s western  _Duel in the Sun (1946)_ (qv). However, with the decline of westerns  in general, owner George Spahn decided to allow a group of misfit  hippies to reside there temporarily in the spring of 1968 in  exchange for minor upkeep of the ranch. This was shortly before  filming of this movie took place. The group called themselves "The  Family" and were led by Charles Manson (qv) and two of their  members, Catherine Share (qv) and Bobby Beausoleil (qv)
