I've been looking at the fortress site for a half-hour now. I may make it down to that area around the time they open.
I find it interesting that they have limited themselves to 13th Century procedures and that they are overseen by a board of scientists. It sounds like they are wanting to do things right and approach it from a true living history point of view. Like Steve, I hope they are able to see this thing through. With enough special events, people with bottomless wallets, and something to draw people into that neck of the woods, maybe they will.
And being close to Dogpatch, maybe it can fuel a revival there, too. OK, so maybe not.
