Well its not really abandoned, after all someone built a house on top of it and have refurbished the living quarters with additional living space.

That aside, one of the things I miss was not buying a missile silo in Idaho when I had the chance. I don't believe any are on the market any more. My biggest concern was the pumping bill (it required constant pumping to keep it from flooding).

Hmm, actually the one in this article is for sale apparently for 1.7M: http://www.silohome.com/missile_base_real_estate_investment_...
