Many families like to have a nice family photo hanging over their fireplace. Or maybe a pretty landscape. My family? We had an architectural rendering by Frank Lloyd Wright of the Guggenheim Museum. So it goes when your dad is an architect. Having been to more than my fair share of architectural historic sites, I can with some authority say that the Frank Lloyd Wright Foundation does a better than average job keeping Taliesin West preserved (especially considering the buildings were designed to be temporary structures) and giving visitors a good history of Wright's work and the role this studio played in his life.
My only complaint is that they really gloss over some of the more scandalous parts of Wright's life, including the that fact that his third wife "stole" FLW's body 25 years after his death, had it cremated, and scattered his ashes in the sculpture garden here. You think they'd mention that on the tour, but you'll have to rely on your architect father to tell you that.
