It depends on your state law whether you can conceal a weapon in your car and not on yourself. In SC anyone can carry a loaded handgun as long as it is in the center console or in the glove compartment and it doesn't have to be locked. I usually just throw an extra weapon with a pocket holster in my center console when I'm out and about. Easy to get to and legal.

To preserve liberty, it is essential that the whole body of people always possess arms, and be taught alike, especially when young, how to use them... -- Richard Henry Lee, 1787
