I live in Ahwatukee between South Mtn. and the Tohono O'Odham people.
Did you go to Cosanti in Scottsdale or Arcosanti up around Cottonwood? Solerie was one of Wrights students. One of those deals where you get to pay for the privelidge of pushing a wheelbarrow. I don't know what Soleri learned, but he did pick up on that little trick and his students pay to do his work as well.
Nothing wrong with that, but I am not sure they reap any large benefits.
Taliesin West is great, and I have visted Fallingwater, and there was was a FLW house in Virginia that I saw when I was stationed at the Pentagon. Some Army Lt. either lived there for free or a nominal fee. He did the up keep and visitors could come through during the day so he had to keep the place pristine. Sort of a caretaker vs rent deal.
