Those into architecture must definitely visit Taliesin West - a working and living memorial to the Frank Lloyd Wright. He built the place and it was actually a kind of living experiment for his little architects/designers/builders. A tour of the place is recommended. Frank Lloyd Wright was definitely a man with a theory when he was building houses. For example, he built all the door ways small so when you passed through to the other side you always felt you were emerging into something. Everything was very geometrical. He was also apparently very stubborn. Case in point: when the buildings first went up there wasn't such thing as glass so when the glass did have to be installed he refused to move anything so in one case they had to cut a hole in the glass to allow for a clay pot that was sticking out!
