E n o r m o u s. One giant room, jammed full of rusted larger than life machinery after the next. It was recently used as the backdrop for the Transformers movie. Not so recently it was turned into a faux mental hospital in the much better film the Twelve Monkeys.
After parking we were first greeted be guard shacks and signage warning us of live razor wire. Finally making it inside the plant, after a wrong turn into a fully operating maintenance building; lights and air conditioner running, we tried our best to not get lost in this monster.
