Back in the day, a small group of transplanted scandanavians built that bath house for their wood stove heated sauna. Used to be, it was not uncommon to see the locals venturing out from that hot sauna, out onto the ice, and take the plunge through a big hole cut into the icy cold water, and then hopping back into the sauna. It used to be a Centre Harbor tradition, and not a bad way to ward off those winter time blahs.......
