any more of girl in second/third pics??

those are from the 2014 Oreg0n C0untry Fair

The group shot with Mom (or whomever) is absolutely stunning!

If you're talking about the first pic, she's a well known exhibitionist with tons of content (old) out there. She might be somebody's mom, but probably not theirs.

Unknown hippy festivals. If anyone has any information, I would greatly appreciate it.

Again, no info.

In your second post: the first two are from Secret Garden Party and the second two are from Empty Hills (a Russian festival, now defunct). In the previous post, that background looks a bit like where they hold Rainbow Gathering. The last two could be Oregon Country Fair. I've seen pictures from there of people painted up the same way, but not those particular ones.
