That was not the thread I was remembering. The thread i was thinking of had some photos of "Sasquatch" bounding across the landscape of Rattlesnake and ....It also might have been a vision of
"Peter, Paul, and Mary"...someone else suggested it was another singing group from the time..I can't remember.
NB
PS: I am of the correct age...but I was NOT at Woodstock (NY) in '69.
