Although dominated by the political sphere (and the media that surrounds it), Washington DC has always been an epicenter of arts and culture. Landmarks, museums, theaters, concert halls and art galleries abound. But like most 'destination cities,' the people who live and work here often indulge their passions away from the tourist traps that draw millions of visitors annually. In DC, locals seek escape where they can find it. And where they find refuge — among the maze of intersecting streets of letters and numbers — has a history all its own. One that has rarely been documented. Until now.
