"california mobsters"

Those words together seem weird. I know they were out there to some degree, but it just seems weird to think about. Is there even any OC in California other than drug dealers, human traffickers, and car thief rings? I've never heard of any gambling or loan shark rings, large protection rackets, large bid rigging operations, or labor racketeering groups out there, but I'm no expert. It seems like it would be fertile territory. (In other words, there's a lot of money out there.) It's also already got a sleazy element (Hollywood). I know there was OC porn operations and Outfit infiltration of film related unions and I assume there are some computer and identity crime groups, but has anyone heard of any LARGE traditional OC activities out there?
