Wow, that's amazing. I love "recent history" stuff like that.
"Recent history" is cool because it's recent enough to still be in decent condition, but not old enough to have attracted the attention of professional historic preservationists.
I also like military sites because they are so often set up in haste and then just as quickly abandoned which can make for some cool relics (they're sort of like modern-day ghost towns in that respect.)
My personal favorites are the abandoned ICBM bases that dot the Western landscape. There are currently 450 active ICBM silos and almost 600 abandoned or closed down silos, to say nothing of the various communications sites and support sites, and closed bases.
You would think that somewhere out there would be a comprehensive list of closed down or abandoned military installations in the US, but if there is such a list, I've never seen it (and I've spent hours on the internet searching.)
Although, knowing a little bit about how the government and military work, I'm actually not surprised that there isn't a comprehensive list. Once a base is no longer active, people tend to forget about it, and even the people who work there just want to finish up their jobs and move on, they're not really thinking about preserving anything. It's the "short timer's attitude" as applied to historic buildings, I guess.
Anyway, great pictures! Sounds like a fun time.
