Larry Hall believes in preparing for scenarios that the Man would have you believe are fictional—Mayan disaster prophecies, pole shifts, alien invasions, that sort of thing. So the 54-year-old software engineer shelled out $250,000 for a decommissioned Atlas F Missile Base in Kansas. "I thought, wow, I can transform it into an ultrasafe, energy-efficient fortress," Hall says. Then he figured that other people might also sleep better 200 feet underground within epoxy-hardened concrete walls. And with a custom retrofit featuring GE Monogram stainless-steel appliances and Kohler fixtures, they could also eat (and flush) in style. So Hall announced a "condo suite package"—starting at $900,000—that includes a five-year food supply (think hydroponics and aquaculture) and "simulated view windows" with light levels calibrated to the time of day to keep you from going crazy. Hall says his silo will have a military-grade security system and electricity powered by geothermal energy and wind turbines, as well as a theater, workout area, and pool with a waterfall. Not a bad place to wait out the apocalypse. Hall is still building this dream silo, but he's already getting applicants. "When they call me up," he says, "they're like, you had me at MISSILE BASE!" With three out of seven floors already spoken for, you'd better get your bid in. You'd hate to be stuck in a moving van when the aliens touch down.
