i suggest taking a moment to watch "Grateful Dawg" documentary... a time gone and come again gods willing...
also the documentary "The Other One" touches a little of the spirit of the 60s before it became a thing... (for that matter a documentary that REALLY catches San Francisco before Time Magazine invented Haight Ashbury is "The Cockettes"...)
i do miss those years sometimes... and i am so very happy to have been present for all the beauty, terror, tragedy, awakening and even the passing of that moment... i'm sure another wave will come, but i cannot see it coming before America ruptures itself with ghastly, world-condemned violence... the Clown-in-Chief is not the enemy... it is his spiritual successor that we ought to be awake to...
