Just took a trip to SC, I printed out the laws of the states I would be passing through. Be extremely careful in Maryland! I had ammo in one locked box and firearm locked in a separate locked box with the firearm in a holster that had a snap retention, with both boxes in the trunk. I read that somewhere so I decided to just be on the safe side. Passing from NC into SC I simply took gun off my hip and into the glove box. This was my first trip so I tried to be prepared, can't ever be too careful!
