One of the first things I noticed about DC when I arrived here were the cool metro stations. Brutal concrete structures, they have so many repeated patterns that any photog’s eyes are immediately pulled to them. They are pretty dark though, making it hard to get a clear shot without a tripod, but they are cool structures. The long deep bare concrete tunnels on the long escalator rides in and out of the stations are also pretty dramatic.
The cold stone waiting seats aren’t the most comfortable things though, especially in the cold weather, and especially when there is weekend trackwork and there is quite a wait for the next train.
