I have watched that video. it is so creepy, like a horror movie, those footsteps and the crows!
DaveR, I don't know how you could go in and for all that time. Were you on your own?
Whatever might they have been doing in that room called "Adult Industrial Therapy Unit?" It doesn't bear thinking about. How could they ever have needed such a huge place?
I'm going to have nightmares tonight.
