I moved to DC not too long ago, and would love to meet someone new.
As for general interests, I follow the University of Maryland men's soccer team avidly. I'm essentially in love with hockey -- though I still can't see the puck when I watch it on TV. Otherwise, I spend a helluva lot of time skating for roller derby.
Also, I've started hiking a lot more. I don't do anything extreme -- though maybe I'll work up to that -- but I enjoy Letterboxing, which is basically treasure hunting and is in the same vein as the more popular Geocaching.
