I don't know if Emmett Grogran ever wrote a book entitled "Mindfuckers" but he certainly wrote "Ringolevio" published, I think, by Avon Press and which is indeed long out of print. I read it in the early 1970's when I was very young and it was my first exposure to radical ideas. At that time my BS detector was not so finely tuned and I remember reading with amazement how this dude from the ghetto became a master jewel thief and safecracker, went to an exclusive NY prep school and screwed all the rich women, became addicted to heroin, went cold turkey, went to Northern Ireland to hang with the IRA, then wound up in California where he founded the Diggers and screwed all the hippy chicks. I don't recall anything about the Farm so I am thinking this is from a later period. I am indeed interested in what ever happened to him. I do seem to remember reading somewhere about a falling out with some of the left's luminaries of the time (Jerry Reubin perhaps??).
