When it became public knowledge that Mark Zuckerberg was building a multi-million dollar doomsday bunker the truth has come to light. He isn't the only one!  Many of the world's elites and mega rich have or are in the process of building long term, lself-sustaining places right under out feet. With tunnels, super highways, farms, etc.  Why are they doing this? How long do they plan to be down there? What do they know that isn't being shared with the rest of us? Is this just a billionaires latest toy fad or something much deeper?Email us at: downtherh@protonmail.com
