sean had it here first. right after i got off the bus this evening, five fire trucks, a couple ambulances, police cruisers, and other fire department vehicles came down rhode island avenue from both the east and the west, converging on what i believe was 67 rhode island avenue, the house to the left of the cream-colored house in google street view above (i couldn't verify this completely as i couldn't get that close. i'll correct this post if i was incorrect).
below are a few pictures of emergency vehicles on 1st street, rhode island avenue, and in the alley. it smelled like an electrical fire. does anyone reading this have any more specific information?
