also, we have this thread:
https://forum.oneclickchicks.com/sear...rchid=14185838
and the "Russian way of Life" thread which contains some of the festival pics you posted above. I also have a personal collection of rainbow gathering pics numbering over a hundred. Many are up at OCC, but I don't know where anymore.
And I'm sure you are aware of Portland's own "Hippie goddess" photographer, David Levine, who posts at Flickr (user David and Emma). Possibly that first pic you posted taken in front of the "thing" on Collins Beach was taken by him.
