I took the tour today. Very interesting. I have seen many pictures from the 1850-80′s. On the tour I would walk into a room and recognize it. It was very cool.
The building is 93,000 sq/ft. There is a lot to see. I am going to have to go back and stay in the house. Take some time just meandering and reading. They have an amazing library, so many old books.
I took lots of pictures.
