I for one enjoy Monday morning commutes, if only because there is usually a fresh splash of color along the Uptown segment of my ride. The grafitti artists work mostly during the weekend, it seems, and each Monday there are new names and statements and pictures up for my viewing pleasure. The building owners always paint over these with some dull brown, which never looks nearly as good as the art they're covering up. Now I can understand being upset if somebody is tagging gang symbols, or if they're painting up the front of your house. But if somebody comes along and, free of charge and out of the goodness of his heart, decides to beautify an otherwise ugly blank brick wall at the back of your apartment building? That should be rewarded, not destroyed. Technically, I know, it's illegal, but lots of stupid things are against the law. Some of their statements are juvenile ("Suck my nuts"), some are paranoid ("The cops are watching me"), and some are just excuses for color and design experiments. But I like it. Especially on a grey morning, sitting in a metal car being dragged between endlessly xeroxed buildings, it's nice to have a little public art.
