Well, that was easy. Hell with finding the back way.
Dean waited until Jo and the guy were gone, then ducked in through the front door, around the counter and into the office. It DID have a door of it's own, which he'd use to escape.
Okay. So. Tapes. Or Discs. Whatever the Hell. There was a small desk and a locked box.
At least it wasn't a safe.
Dean pulled a few picks out of his pocket and went to work on it. At least it wasn't anything complex. It was about the size of a filing cabinet but better metal, so he couldn't just bend the door back and pop it open.
