There's a cool little dog park in a triangle formed by the intersection of New Hampshire, S Street and 17th Street. People just bring their dogs, let them loose and they play. It's awesome and right in the middle of my walk to work.
I've taken to stopping on my way home to watch the dogs play. Some of them are super excited, some of them ignore the others and sniff the ground, and some are scared as hell and hide behind me. It's very interesting, relaxing and just plain fun to watch. I kind of want a dog. Maybe I should get a job first.
