You just gotta think of what you're doing it for. If you're doing it for the art and the fame, have some respect and do it where people will look, and where it will stand out and stuff. But I wouldn't do it on people's cars, churches, and houses. Police cars are an exception =] If you're doing it not just to destroy property but to let people know your name, you know? And make sure you have respect of what you're saying, like you wouldn't put "fuck the system" by an elementary school. Just my thought.
