Do you know what this is? It is a patch of dog pee-soaked, filth-speckled city sidewalk. But it's beautiful. I am proud of myself for stopping, for noticing, for capturing. I like to imagine how many people stomp on it every day, this quiet, soiled square on West 96th Street. Who are these people and where are they headed? Have any of them ever seen, really seen, the art on which they so furiously tread, the art to which they unwittingly and incomparably add?
