Having moved from CA to Idaho in August and having looked into CCW issues in CA I found out a few things.
The local city/county can determine it's own CCW parameters and if they will issue them or not. Isleton is one municipality in Northern CA that for a period of 4 years issued permits to anyone that could pass a background check. Generally however, things in CA are moving in the opposite direction.
I for one carried illegally from time to time in CA because my travels sometimes took me into areas that were crime ridden,.. the violent kind. Like the saying goes, "Be judged by 12 or carried by 6". Besides, it is not a felony to carry a weapon if you are not a convicted felon. In most jurisdictions it is a misdemeanor. In any event, when it comes down to personal saftey, I would carry.
Unless you look like someone who may have spent some time bending the laws and do things that draw attention to you either on the street or in your vehicle, no one is likely to ask if you are packing or to search you.
