I first saw the building in a copy of the World book Encyclopedia and this along with Fallingwater, inspired me to get into engineering/architecture, so this was a building I wanted to see. As part of my retirement I'm trying to see as many of Wrights buildings as possible. The tour was very good, my guide was on her second "solo" tour as a guide. I thought she did a very good job, a little nervous on parts, and was asked some questions were out of her knowledge base, but with time she'll do well. The site is exactly as I envisioned, right down to a Royal typewriter on a desk. My only complaint is the inability to take photographs. i understand when it is still a "working facility" but the research tower is no longer in that status. I hope someday, they turn the Frank LLoyd Wright part into a museum and allow photos. i would be more than willing to pay a fee to enter. I've paid $40.00 to tour a house in Iowa, $115.00 for Taliesin West (which was a bad tour by the way) so a fee to see this and have a little more freedom would be nice, and I think a help to the maintenance and upkeep. The other problem is the reservation process. The website could use an update, more user friendly. Otherwise, if you get the chance go see this place. The History and story behind it makes it worth the trip.
