Most people don’t realize that there are giant structures, factories, research labs, scientific test sites, huge military bases and even large malls that exist completely underground. Some of these places are well-known, but others are shrouded in government secrecy and hidden away from public knowledge.
Large, famous underground areas that are open to the public include Montreal’s RESO, Toronto’s PATH and Japan’s underground shopping streets. There are also many underground military bases that have been publicly admitted. Some of which are common knowledge like the Cheyenne Mountain Complex.
But, some have claimed that there are entire self-sustaining cities with their own roads, way of life and maybe even governments that exist miles beneath the Earth’s surface hidden from the public’s knowledge. Seems pretty hard to believe, but I don’t doubt the technology and funding exist to make it happen. The US government has a so-called, “black budget” of over $51 Billion. That’s American people’s money used for classified projects only. ( http://www.wired.com/dangerroom/2012/02/pentagons-black-budget/ )
It has also been claimed among outspoken military that there are super high-speed trains underneath the United States… possibly even the world. These trains are apparently how some of the military travel. The rumor is that the technology utilized in this transportation surpasses much of what we have on the surface.
I’ve heard the train thing is true, but only those in the know, really know.
