Union Station
When I lived in DC, I used to like to wander through Union Station in the middle of the night or around dawn when it is almost empty of tourists and some commuters. Took the pics in the day time, sorry :(
I did look for a certain homeless woman - she was large, had a bleached face with striped tattoos on her cheeks, wore dark sunglasses and a turban. She hung around the front of US and resided in one of the bathrooms. Anyone remember her? Last time I saw her was in 2001 - I think the first time I noticed her was maybe mid 90s. I didn't look very long so I either missed her or she's moved to a different place.
