websters dictionary defines this as:
GUERRILLA: a member of a small defensive force of irregular soldiers, making surprise raids.
ART: human creativity. skill.
so, there you have it. guerrilla art is typically found in larger cities. metro areas, frequented by lots of people. i love this!! it is different from graffiti, much different. it's not meant to be destructive. on the contrary. it is meant to put a smile on random faces. sort of like random acts of kindness, which can also be guerrilla art.
