Off-topic: I'm not an architecture buff and still found the (not-too-cheap) tour of Taliesin West well worth the time and money. Worth considering if you're ever in Scottsdale AZ.
Paolo Soleri is a really interesting character
'Tis true. I worked with him fairly closely for five years (1992-1997), so knew him well. Happy to do an AMA for anyone who's interested in the subject.
