One of that era's icons remains — a massive underground bunker designed to protect all 535 members of Congress and their aides against nuclear war. Dug into the Allegheny Mountains at the Greenbrier resort in White Sulphur Springs, W.Va., it once had 75,000 gallons of water, a power system, medical and food services, 30-ton blast doors, art of the last days of Pompeii and a mural of Washington scenery that was capable of changing leaves on the trees, depending on the season.
In private Facebook groups, wealthy survivalists swap tips on gas masks, bunkers, and locations safe from the effects of climate change. One member, the head of an investment firm, told me, “I keep a helicopter gassed up all the time, and I have an underground bunker with an air-filtration system.” He said that his preparations probably put him at the “extreme” end among his peers. But he added, “A lot of my friends do the guns and the motorcycles and the gold coins. That’s not too rare anymore.”
