Arcosanti's a trip. I stayed overnight there. It's crazy cheap. If the Mos Eisley Spaceport were in a post-apocalyptic future written by Douglas Coupland, it'd be Arcosanti.
This book is legit outsider art. Paolo Solari is probably insane, but since he's an insane architect rather than an insane cult leader he gets a bye. It's kinda funny - one of the few things he ever did for money was design a foundry building. It was there he fell in love with slip-cast concrete. So now everything is slip-cast concrete. he's even got a foundry. And hey - $300 a week to run off and join the Lost Boys while eating hippie chow. Just pick your season carefully.
It's a hell of a place.
