I work with a company that doesn't permit guns in their workplace, as many others I would assume. I have to drive through a "not so friendly" area to get to work, and leave my gun locked in my car, I know someone else that does this, but can't help from feeling a little nervous. I always keep the serial number with me in case my car gets broken into and the gun gets stolen. Anyone else leave their gun in their car, locked of course? Or use car holsters?
