That green paint seems to have been popular in that era... all the rooms in my house are painted in that green under all the paint layers accumulated over the years.
Alex: well no this isn't the first padded room I've come across. I jumped ahead in my sequence of photos to get to my Europe trip online. There is a room at one of the locations on the main page with a large padded room; it had a thick rubber material on all four walls. I guess you could call it an actual "rubber room."
They are pretty rare to come by though in my experience... I only know of about 4 of these types of rooms. Sound proof and / or stain proof seclusion rooms seem to be a more popular solution. Then again, many of the pads in these types of rooms are held up by Velcro or a similar temporary method, so they might have been removed and an explorer would never know. I think I remember this hospital having another set of these green pads laying around outside, and I've seen a dismantled padded wall at another hospital in the states.
I used to leave a card in an obscure place or write my name on a chalkboard when I started, but now I don't bother.
Getting into some really untouched and risky places and leaving something like that behind can make the location impossible to get back into once someone realizes people are sneaking in; I've seen it happen more than once.
HaHaHa!!!!!! Somebody get my Combivent!!! Ah what the hell, Uvula / Vulva it's all the same. Can't ... stop...laughing... sucks on inhaler again. I'm gonna get smacked the next time I get lucky cause I'm gonna start laughing and she ain't gonna understand why.
Regarding the speaker, I think they played horrible noises & music (Perry Como) to torture the poor soul in the room and they took turns looking at them in the mirror. Am I right Lynne? 8-)
