pigrabbitbear writes "'I was inspired with a very powerful message around 1980 that I needed to build a shelter for 1,000 people deep underground to survive something that was coming that was going to be an extinction event,' he explained in an extensive phone interview. 'That's it, that's all I had. But it was powerful. So powerful that I had a successful business with 100 employees and I took time off to go up into the mountains and search on weekends looking for an underground mine or cave that could be cartoned and converted.' Today, Vicino is the owner and founder of Vivos, a company that sells space in luxury survival complexes around the country. It's what he likes to call 'life assurance'--mini underground cities, in effect, for people ride out the end of civilization in a community setting with good food, television, even a potential dating pool. He says demand has increased 1,000 percent this year compared to last—itself a 1,000 percent increase over the year before."
