These are comments I have wanted to make but didn't want to appear argumentative and tick anybody off. I was very much a hippy in 1968 to 1971 living in an apartment on Haight St. Hippies were part of a subculture mostly shunned and hated by mainstream culture. It amuses me now to hear aging cheerleader types claim they were hippies. Go figure. Anyway, with that said, although Alcala pictures show him to look like a hippy, most the these girls do not look like hippies to me. One exception being singer girl. I think he zeroed in on a certain type. Prepubescent looking girls and atttractive girls that he thought would be flattered to have a photographer feed them a line. Most of them look like "straight" young women. The fad of girls not shaving was a very brief fad probably not practiced by more than 10% of the girls who were hippies. I myself tried not shaving for a few weeks a couple of times but it made me feel very unfeminine and it was a turn off to guys. For this reason I would not easily dismiss hairy armpits when deciding if someone was male or female. Alcala saw women as sex objects and I don't think au natural earth mother types were his thing. Person hanging is a male, guys!
I did find WildHuncher's diagram of a person being hoisted up by another man brilliant because until that explanation, I could not figure the picture out at all, with the legs being too close for a backbend.
There, I've finally said all I have been wanting to say.
