I have been an AZ resident for 12 years now. My family and I vacation in CA Almost every year. We literally just got back from 3 days in San Diego and 3 days in the Sequoia Forest (which was amazing by the way). CA is a beautiful state but the gun laws are ridiculous! My firearm of choice is my S&W M&P 40. Since this weapon has a 15 round magazine...not an option to carry across state lines. My other option would have been to take my .38Spl 5 round revolver. As other posters have stated, this would have been unloaded, locked up, separate from ammo, and in a compartment that was not accessible from the main cabin of the vehicle. BUT,.....we rented a minivan that does not have a separate trunk area!!! Although it pains me greatly, especially when I am traveling with my family, when headed to California.......I leave my guns at home.
