Have you ever been to California to see "ghettos"? Every State in the union has "ghettos". Last week my son and I went to Oregon and Washington to watch Minor League Baseball (do to the SF Giants needing some pitching help) and their high A league team played in the NW League.
Portland has Graffiti all over the place, SF has none do to the fact that when Graffiti is painted it is covered up almost immediately. Favorite targets in The City have colorful murals painted over, costly painted murals when vandalized are felonies.
