One nitpick--I doubt there's any hippie enclaves in Arizona. Trust me, I live there, the enclaves we tend to get are either neo-nazis or the survivalists in the woods.
I lived there too. And yes there are hippie enclaves. If you don't believe me, drive south I-10 from Phoenix to Tucson until you see a sign for Arcosanti. It was a project started in the 70's by Paolo Soleri (student of the great Frank Lloyd Wright) to build the first ever Arcology. It's pretty much entirely made of hippies now. There's also a bunch up near Sedona and Flag.
