Only two states in the US w/o CCW are Illinois and Wisconsin. Every other state has some form of it.
Unfortunately, in California, you need to prove how wealthy, powerful and important you are that would make you a target for violence. Average Joe? Good luck.
Kali has easy to get CCW in some (rural) counties, and very tough to get almost everywhere else.
if you live there and want a CCW, i'd suggest investing in a vacation home in one of the counties where it's easier to get. (or investigate other ways of "establishing an alternate address", i.e. find a friend to rent a room from, or whatever.
IIRC, Fresno County issues about 500 CCWs per year. someone who's actually there will have to report on what counties are easier than others. IIRC, Humboldt has a lot too.
