On our way to Houston for Thanksgiving, we stayed in Willis, Texas for a few days beforehand. There were many times when we drove down I-45 we passed the Prison Museum and Jim would say that he wanted to stop there. Well, we finally were able to take a trip there. The actual prison is on the west side of I-45, while the museum is on the east side of I-45, just north of the huge Sam Houston statute (which we also seem to miss stopping to see).
