Thanks. That's a good thread. I was there only part of a day. Had a day off in Phoenix, and a colleague and I drove to Flagstaff via Arcosanti and Sedona. Disc

Thanks. That's a good thread. I was there only part of a day. Had a day off in Phoenix, and a colleague and I drove to Flagstaff via Arcosanti and Sedona. Discussion on that thread gives a lot of information about what has happened since. The book I bought in their store had a lot of ideas about huge cities built as monolithic structures, unlike what is on the ground now.
