Graffiti For U & Me
When friends visit New York City, they're often surprised to learn that much of the graffiti they see around town is "legal". From massive art exhibits to designated mural walls...

The city allows graffiti in public spaces, especially in run down areas, to add color. "Legal graffiti", for the kids, to make them happy, and their neighborhoods less drab.
