Yes, there certainly are some impressive spaces here although I've always found it interesting that the US has never seemed to develop more extensive facilities like Europe. (thinking of places like OWK, Studio Avalon, Warsaw Prison etc)

I've always been fascinated by the idea of being checked in to such a place for an extended period of training and conditioning.

edit
The old mill in Mass used by Goddess Nemesis also looks like an amazing space.
