If you run or bike on the , you’ll have to go through this tunnel. I think it is under Massachusetts avenue. it is all woodsy around and way below the street so hard to know from down there where exactly it is located. I guess I can investigate it on the map and figure it out, but I don’t feel like doing it at the moment. Maybe you can figure it out and leave a comment about it. It was around 8PM when I took this picture and was getting dark, the trail was fairly empty by this time, but even then I spent at least 10 minutes getting the right shot. Bikers are very fast and by the time you get in the middle position the camera and trying to take a shot someone is coming from either end. I took about five shots and this one was the best out off all of them.
Way cool
