You have to love it when you're illegally inside some abandoned looking building and you find a sign-in book that shows when security entered and left the building on patrol...

On the one hand, that's a little creepy, on the other, well, you can tell what days of the week they don't seem to come around, and what times of the day they show up... Probably not the best security technique I would say... Oh yeah and leaving all those doors open didn't help either. ha!
