Buy A Dish
Ever wanted to own a satellite communications dish? For post-SHTF reception or perhaps doing SETI work? Or just because it is cool owning a piece of history? This is the ground station that received the first pics back from the moon:

Jamesburg Earth Station, Carmel Valley, California
The 21,718 square foot secure structure is not a bunker, but with walls three feet thick it could make a good shelter. It comes with 103 acres and can be purchased for just under $3 million, with adjoining properties also available. The dish is 97 feet in diameter, and if you felt like playing with it, according to the Monterey County Herald it costs $3000 a time in electricity. Full details of the sale here.
