So to the National Mall Circular Bus. I got off close to the Washington Monument. I had left my camera in the bag, thinking that for still pictures, the phone would do. After arriving at the Washington Monument, I switched over to my SLR, which allowed for a wider angle, wider than the phone. Plus, the phone had a unsettling delay between pressing the shutter release and the actual shutter release, of a second or two, so it was easy to miss getting what you wanted, particular on a bus.
At the center of this "tour" seemed to be the Washington Monument, from the Mall, from the Jefferson Memorial, or the Lincoln Memorial.
