Strangest thing, but I've seen it about ten times on my way work in the last three months. Around 6:30 a.m. there are three girls who are obviously prostitutes near the intersection of 13th and Mass Ave. I'm not sure if they're going home or what - I've seen them getting out of cabs, unmarked cars, and crossing the street. They're sometimes together, sometimes separate, but always dressed for the job in a very business-oriented and cleancut part of town. Very, very strange.
