I went to Hot Springs, Arkansas this past weekend, and we went to the baths at the Quapaw Bathhouse. It was great. Incredibly relaxing. We went to the open baths where there are four pools, four different temperatures to choose from. No chlorine, just pure water from the earth. It comes out at 140 degrees F, and they cool it between 91–104 for the pools, and they serve you chilled water to drink. Afterwards your skin is soft.
Very interesting little bit of history there. The water still comes up from the earth. In the middle of downtown you can walk up to the multiple spickets in the center of town and get pure mineral spring drining water and fill your containers.
