Found David Zinn of zinnart.com creating an optimistic chalk scene. [photo 1] [photo 2] Here is an idea that wouldn’t have any controversy. I noted that David’s home sidewalk was one of the best in the neighborhood for snow removal. He acknowledged he has a personal feeling for sidewalks. If the city paid lots of sidewalk chalk artists people would have another reason to keep sidewalks clear – for art. Two problems solved – not enough art and not enough clear sidewalks in the winter.
