Listed on eBay, is a real honest-to-God missile silo for sale...

A property for only the rich and eccentric! Built in the 1960's at a cost of over $130,000,000, this is one of the most unique properties in the world. These sites were designed to withstand an atomic blast and include over 45,000 sq. ft. of underground floor space. Build the ultimate secure home or a secure archive, etc! Located only minutes away from Denver and an International Airport. We could not begin to estimate the value of the underground structure, so the property has been listed at a price only slightly above the raw ground and water valuations. Own a piece of history and the sole property of it's kind on the planet!

I saw a television program somewhere that documented a husband and wife who converted an old missile silo into a home. You figure, these things were built by the government to withstand nuclear attacks. And I imagine it stays pretty cool in the Summer.
