I used to know this lovely Aussie girl (via the internet) who told me hippies are called "ferals" down there. I always loved that. It has a beautiful descriptive quality to it. She sent me pictures once that I now realize were from a doof, judging from your description.
We don't have anything like that here. Maybe up in the NW, I don't know. The Rainbow Family gatherings have gone so far underground that I am not sure they even still exist. That was the closest thing we had to what you are describing.
*sigh* I miss my hippie friends desperately.
