About 500 people took part in the annual South Boston tradition of plunging half-naked into the freezing waters of Dorchester Bay to ring in the New Year. The L Street Brownies is one of the oldest polar bear swims in the country. This year, the temperature was only 13 degrees; factor in the windchill and it’s hard to imagine how people do it. Swimmers were given extra courage by a bagpipe band made up of players from the local firefighters and engineers unions.
