What are the regulations for a non resident to drive into CA to compete at ATA shoots? I'm referring to the very restrictive gun laws pertaining to non residents bringing and possessing guns when in their state. I know when I have driven to CA. in the past, I have left my carry gun at home because my CO permit is not allowed with reciprocity there. What's the real deal there for those that would like to drive to CA. for the State Shoot? Are there any other states that have laws making this difficult, as well? I heard that Cook county in Illinois you can't even drive through with guns because of local gun laws.
