Much to my chagrin, I have never explored the Kirkbride building at Graystone. Too much drama and too many legal hassles have surrounded it in recent years, and the rewards were far outstripped by the risk. I have been told by those that have been inside that the outbuildings on campus were really the best part of the site. I, obviously, like that a lot so I am going with it.
My own bias aside, the outbuildings at Graystone really were remarkable structures. They were beautiful in their own right and had tons of cool stuff left behind in them. To this day the outbuildings there are one of the top hospitals I have ever shot. The two days I spent there were also two of my favorite days I ever spent exploring. The first was just a fun group exploring day, the second I spent alone in the surgical building in blazing heat and choking humidity, in the middle of a thunderstorm.
