Letting your guard down on the subway generally isn't a good idea. But your pants?
Several MBTA riders braved the cold (and hygiene risks) today as they rode trains pantless as part of the fourth annual No Pants Subway Ride in Boston.
The event, which started today at the Alewife Red Line stop in Cambridge, is organized by the Societies of Spontaneity. The idea originated nine years ago in New York by ImprovEverywhere.com.
