There is nothing better than a warm Sunday afternoon spent walking. This was a chilly Sunday afternoon on which I was dressed for a warm Sunday afternoon, but I walked, and it was pretty good all the same. I started out this walk on 79th street, trying to pay attention to details I would normally overlook. Heading south, brick and brownstone made way for sleek and chique glass. By the end of the walk at 56th street, the light was dimming and all I could focus on were the shapes and shadows of buildings against the sky.
