Just FYI, The Library of Congress has some pretty neat period pictures. I have a bunch of them set up as desktop wallpaper.
The cold war may have been a lousy idea; but the aesthetics of letting brutalists do apocalyptic machinery are pretty compelling.
Now, though, I have to wonder what the Hutterites plan to do with it. Old military sites tend to be pretty brownfield; so aside from looking really cool it is likely worth less than more prosaic chunks of the middle of nowhere. Are they just going to farm around it?
