Dad always called these characters the "hippies in the red dresses". Personally I remember them hanging out a lot near the "newly transformed" section of the old Ghirardelli Chocolate Factory "above" Fisherman's Wharf, circa 1967 or so.
On this same wave length, one of my Catholic grammar school classmates ended up marrying one of the "Moonies"--as in Reverend Moon, where the marriages were arranged. As far as I know she is still married to the guy, too. Guess the Reverend made a good choice for her, at least!
