There are no dry paint signs. That simple fact transforms wet paint signs into an event: Transitory public performances whose main intrigue is their fleeting nature. Which surface was painted? Is it still wet? Can I touch it? What will my fingertip look like dotted in color? Did it happen today? Yesterday? At all? Running across wet painting in action is a little like catching Santa Claus wrapping gifts. I was oddly thrilled to witness this sidewalk performance. The artist wielding the red roller was proudly in the flow. Which changed me. Next time I come across a lonely wet paint testament, I'll look for clues about the painter rather than the painted.
