Swimming in Dorchester Bay on New Year's Day

For over a century the L Street Brownies, a swimming club in South Boston, has sponsored a "polar plunge", a dip in the waters of Boston Harbor. Yesterday, almost a 1,000 people dipped. The water was calm and, at 46 degrees, comparatively warm. The air temperature was 42 degrees, with wind gusts of 25 to 28 miles per hour.
