Years ago I was visiting NYC and staying in a hotel on the upper west side. I got out early on a Sunday morning to buy some bagels, and there were cool little sayings written in chalk on the sidewalk every 20 feet or so, sometimes a cute little cartoon. They were all over the streets. The artist had spent the entire previous night writing these all over the upper west side.

The word got out about them, and it made the local news first, then the national news. Eventually the artist was identified, and I have always felt lucky to have experienced them personally, especially so early in the morning before they were scuffed up and disappeared. Now that I think about it, that's probably why he did it on a Sunday morning, when there would be less sidewalk traffic, and his exhibition would last just a bit longer. It was before digital cameras, or I would have taken pictures of all of them.

Its things like this that make NYC so endlessly fascinating and cool.
