Most people probably just walk on by, but I've always been a little bit curious about the signs and symbols spray painted in bright colors on paved surfaces in most cities. It is a language I don't pretend to understand, yet the patterns can be interesting to photograph. Could be I was just plain oblivious like everyone else, but I don't remember seeing these markings when I was a kid. Perhaps what they really signify is that our infrastructure is aging and in need of repair.
