Unless you're law enforcement or a celebrity I find that nearly impossible to believe.
It is easy to get a CCW in almost any of the rural counties in California and the permits are valid state-wide. Obviously, the "unfriendly" counties are usually the ones with large population centers. Bay area, LA and SD. There have been movements to try to get a "friendlier" sheriff elected in San Diego, but it just hasn't come about yet. Orange County used to be a "friendly" county as well, but that has ended. When I come down to San Diego, the permit issued to me by the Sacramento Sheriff lets me go all over town, with certain restrictions, of course.
