I remember reading an alternative newspaper in 1969 about Woodstock. I took it home, and my parents promptly found it and got rid of it

The "hippie vibe" was late in coming to my neck of the woods, but came it did. I would guess it lasted in my part of the world from 1969 to maybe 1973.

The one permanent change I think it's wrought in American culture is "do your own thing", you don't have to fit in exactly, you can lead your own life. Of course, the old school conservative ethos of doing as your parents say or as your "elders" recommend is still with us, but at least now there is a strong viable alternative.

I envy you older DU'ers that actually got to BE hippies. It wasn't really available to me in my limited thinking in 1976. I think hippies rock !
