I do. Was young and felt free. Did not take drugs (never even tempted) but listening to music/singing/dancing were purely joyful (was that a high?) and that music has never died. For me.
Even tho am not American clearly remember the moment we heard JFK was assassinated and felt huge sadness & shock. Felt like an end of an era come too soon. Difficult to describe all the emotions.
Since then have realised morals changed in those times and there was manipulation unrecognised by us. It was a simpler world then; more innocent. Not so materialistic (for me). I always retained my belief in God but moved away from (man-made) religion over time.
In retrospect i realised i bought into the flower-power vibe of peace but also believed countries needed to have defence systems. i.e wasn't immersed in it. Grew up very close to nature which I see as a privilege now.

So to answer your question, the main difference (personally) is i no longer feel free. Everything is controlled. Unreal
