Smith Mansion, Wapiti Valley, Wyoming
We didn't get inside the great house, but I can only imagine that its is cooler on the inside than it is from the outside. Francis Lee Smith spent years building the house almost completely by himself. The house is 5 stories high and now abandoned, but the family is trying to save it. Mr Smith dies in 1992 when he fell from a roof as he worked on his dream.
Here is a great article about his story.
