it was very interesting to see the old structures from the 1800s. I enjoyed it since the original purpose of the location is what I currently do for my career. I took my wife and son to it they enjoyed it, which is ironic bc my wife does not like history. It is clean and not a bad way to spend time when the weather is nice here in Yuma. I believe it is $4 to get in but when I went on a Sunday it was free.
