Drove over the mountains to Yuma and got set up in the Yuma Cactus Garden RV Park. While in Yuma, I visited the Yuma Territorial Prison which has been well reclaimed and is a good self guided tour. The prison sits on the banks of the Colorado River. It was interesting to see how little water is left after all of the states north have siphoned off their allocations. The river can be waded across and the water never reaches over your chest. Yuma is a popular destination for many "snowbirds". Many of these winter visitors are Canadian.
