I've visited this place seven or eight times, so I didn't walk away with many pics on this trip. I did make some new discoveries about security however.
I saw a security camera that I've never seen before. It's mounted to the building closest to the train tracks. At the opposite end of the building from the guard shack. Oh, and there were two guards. Their vehicles were parked near where they stood gabbing away. One vehicle was a dark green truck. The other was a dark grey car with an orange security light mounted on top.
I went with a fellow UER member. We went in and came with no problems whatsoever.
My advice is to not get too close to either end of the building when entering and exiting. Sorry I don't have any pics of the camera.
