I went into an abandoned one and stood till morning. That had to be one of the craziest nights ever. We all pretty much crapped our pants in there. Not for being crazy, but cause, we were scared...
Anyways I think they're an ok place. Just really badly run. I've been to way too many where patients get abused and it goes unreported. The workers there have a pact or something. Almost all of them are drugged at one point, and the one's that can get help, don't get it.
So the only problem I see with them is that they're just so poorly run right now that there's little use for them. If we could completely overhaul the system and get some people that don't take out their anger with the patients, it can be a great place to teach people.
