Where To Start

I saw so much during this trip to DC, I hardly know where to begin. I guess I'm going to just do something roughly chronological, so here's the view through an outside corridor at Union Station when I first got off the Metro in town. I love these sorts of shots, but I don't know exactly how to make them work. Maybe I should crop it so that it begins inside the long string of archways... And is it a better shot with the people in it than without? This might be a good candidate for High Dynamic Range photography, but I don't think would let me use a tripod among all the scurrying people.
