ATCHISON, Kansas -- If you have a recreational vehicle, you could have a spot underground at the Vivos Survival Shelter and Resort .
An old, man-made cave just south of Atchison used to serve as storage for the government. Now it's turning into a temporary home for people willing to pay for advertised survival.
A California company named Vivos is renovating more than 2 million square feet of underground space, turning it into the world's largest doomsday shelter.
Vivos founder and CEO Robert Vicino said he searched 30 years for a cave like this. He said the limestone bunker is in a perfect location here in the Heartland. Vicino said it's central for people all across the country and world, seeking refuge from catastrophe.
"Perhaps an asteroid, perhaps something from space or maybe it's just the heating up of terrorism or nuclear event somewhere in the world," Vicino said.
