My hometown was an internationally famous resort for the wealthy around the turn of the century, for the medicinal properties of taking hot baths. It was Al Capone's favorite holiday destination and he made it his informal Southern headquarters. The bath houses on Bathhouse Row, as the street is called, are considered landmarks and have been lovingly preserved as examples of Victorian-era architecture.
Those open air springs of hot water are all over downtown. Many people take empty milk jugs and fill'em up with the healthy, natural mineral water available at public taps for free.
Oh, BTW, the name of the town is - naturally - Hot Springs. It's the only U.S. national park located in an urban area.
