Missile Bases : not just for missiles anymore!
"Thank you for your interest in the unique underground structures we offer for sale. These historic cold war structures were each built at the cost of millions of taxpayer dollars. These earth-contact hardened nuclear-proof structures are some of the strongest construction ever built on the planet. No cost was spared. They are the 20th Century’s counterpart of the fortified castles of past centuries. They bring new meaning to the word "shelter". Centuries from now they will remain."
