There's a subway war brewing

There's a subway war brewing between Washington D.C. and NYC, and it ain't pretty. What started with a NY Times writer spotting an anti-NYC metro poster on the subway in D.C. (essentially, it claimed NYC subways are awash with "rats the size of house cats"), has now erupted into a full-fledged trash-talking affair. The following attack on D.C. (its subway map "has all the sophistication of Fisher Price") only perpetuated more attacks; specifically: "Welcome to Dumbassville (aka Park Slope). Population: you." Oh no you didn't! [Gothamist]
