Since 1920, a group of hardy swimmers has celebrated New Year’s Day by plunging into the frigid waters of Vancouver’s English Bay. The custom has spread to the US, where chapters of the American Polar Bear Club have established themselves in a number of states known for their cold winter weather. In Sheboygan, Wisconsin, more than 300 daring swimmers brave the ice floes of Lake Michigan to take their New Year’s Day swim. The Sheboygan event has gradually expanded into a day-long festival, with a brat-fry, a costume contest, and live entertainment. Discuss
