I walk a dog in SW (wharf) and I’ve had a weird experience on N St too. We turned onto N off the main road going toward the Anacostia trail. A dark green SUV pulled up a little behind the dog and I and followed us for a block. At first I thought they were just looking at addresses (it is a residential area…) but at the end of the road they pulled across the sidewalk and then sped away when the dog and I looked back at them. She was on edge too. Part of me wants to give them the benefit of the doubt (lost, didn’t realize it was a dead end, whatever) but it was still spooky.

Edit to add: I’m in my early 20s but a group of middle schoolers asked me if I went to their school while I was at a bus stop so I guess I look younger.
