CA leaves issuing of permits up to the locales. Mostly the 'good cause' is used to deny to any but the politically connected. Several of the more rural counties are virtually 'shall issue' because of the local political situation. Unfortunately, as stated above, CA does not recognize anybody else's permit or issue permits to non-residents.
I find it annoying that I must disarm in the state I have to travel in where I most need protection. In fact, I have considered dual-residency as my CA address would be one of those almost-shall-issue counties.
But, when I actually consider CA residency...better sense prevails and I refrain.
People don't like to be meddled with. We tell them what to do, what to think, don't run, don't walk. We're in their homes and in their heads and we haven't the right. We're meddlesome.--River Tam
