to vote in 68 you had to be 21, don't forget, and that leaves only a small fraction of boomers enfranchised. i was born in early 49, and wasn't able to do more than support clean gene. i was in the bay area during 67-71, and don't understand how anyone born later than mid fifties is considered a boomer. some numbers person made up the year span, not a sociologist. if you didn't experience the fifties as a schoolage person, living at home, the 60's didn't have the same effect. i look at my generation as those coming of age in the sixties. we were the last generation to be able to just take off to a national park and start hiking, without reservations or a hiking plan. we could drink the water, too. and don't forget birth control. we could get it and stds were not rampant, so, you figure it out. read HST 'wave speech' (google it) for a fairly 'right on' view of the era, you didn't even have to do drugs to feel it (i didn't till the 70s). my first presidential vote was for mcgovern, i had crossed over in the primary in montana to vote against nixon. that persists as the weirdest thing i have done. read mark morford 'hippie crap saves the world'- end rant
ps what you say about the sellout @75 was exactly true. i had children and a garden all late 70s, keeping the hippie ethis alive, but off the grid.
