In January we went to Texas and Oklahoma. This photo was taken at an observation area along the interstate in Oklahoma. I thought it was a rather strange place to find graffiti, but I guess even rocks are fair game.
I have heard graffiti referred to as vandalism, but in most cases I believe it to be art. I'm not sure I feel that way about drawing on these rocks though. This looks more like vandalism to me.
Wikipedia defines graffiti as writing or drawings that have been scribbled, scratched, or painted on a wall or other surface, which dates back to Ancient Egypt and Ancient Greece. In modern times, when done without the property owner's permission, it is considered vandalism and a punishable crime.
Graffiti artists prefer to be referred to as writers. The first modern day Graffiti Writer is considered to be a person called Cornbread, from Philadelphia. In 1967, he started writing, or tagging, on walls to impress a girl. In the 80's galleries started showing graffiti as art.
