i do so hopefully expect to be contacted by the police if only to educate them on the legality of our actions!
They may well know the legality of your actions, but they also have a job to do.
Agencies throughout the state - but mainly in southern California - have gone through a goodly amount of updates on these laws in the last year since a small group has been pushing the open carry thing. It really has not been that big a deal. Most the cops you are likely to encounter will check your weapon and ID, and then be on their way.
I live in a rural part of the state where there are many times more guns than people, yet no one here feels any great need to openly carry. Personally, i think it's more for show than any true sense of self protection. But, if that's what you want to do, you have the legal right to do so.
