It is completely deserted except for the tower dome! Thats an FAA weather dome iirc, I just remember the FAA uses it for something, lots of fences and still active.
At one point during the night game, we were behind a squad of 6 people and we hadn't asked them the code word for our team yet (our pointmans call to do so whenever), we were stopped for 5 maybe 10 minutes, all guns pointed at these guys as they protected the objective. Then finally we found out they were friendly, got ready to help them, when Game Control called it over. The Objective hadn't been taken, but some fucker on the other team was going to start a fight with some other guy for a pointless reason.
