What to do?
So far I've never run into any place I couldn't carry except to work, and in a couple of hospitals. What I've done is unload my gun, loop a cable lock through the action, lock that in the glove box, lock the glove box, then lock the car.
I figure that way if somone does break into my car and steals my gun, I can at least claim I did everything I could to disable it.
For God so loved the world, that He gave His only begotten Son, that whoever believes in Him should not perish, but have everlasting life.
John 3:16 (NKJV)
