Today John, Jan and I went to visit the Casa Grande Ruins. It was a pretty neat place. We saw a short movie then went through a small museum. Then there was a tour guide who gave us a great tour of the Ruins.
The home there is known as the ("Great House") is still there and they think it has been there since around 1350 C.E. This is one of the largest prehistoric structures ever built in North America; its purpose still remains a mystery.
