Haunted? That's just superstition. There are no such things as ghosts, Gods and angels. All that's stuff is made up. But if you want to check out some eerie places, check out this database (Urban Exploration Resource: Location Index: United States > California
) of abandoned places worth exploring! Always a good time with a couple of friends. The only abnormal presence you'll find is probably a homeless person shooting up heroin, but they're generally harmless. Be aware, make sure what you're doing is legal though, you could get nailed for trespassing if you don't mind signs and fences. Have fun!
