make sure when you guys travel through other states you know the laws reguarding ccw. ie; carrying in your vehicle, bars, public buildings, etc as well as notification of leo during traffic stop. also some states when in your vehicle have funky laws like minimum amount of actions to ready the firearm, to prevent carrying one in the tube. and make sure you are in accordance with federal mandates on traveling with a firearm through states where your permit is not valid.
