BS Some people put on the internet

Didnt know if you were kidding or serious. My uncle worked on one in Pennsylvania when I was a kid. Early 70's. They ran electric and the tunnel section he worked on was 3.7 miles. This was common knowledge back 40 years ago. No kookiness, or imaginations or tin hats. Its just what the military was working on. Where do you think all the important people go in the event of a nuclear strike? They knew where they were gonna go, and they had it built. Heck how old is Cheyenne mountain? do people deny that exists too? Everyone does know whats below Denver airport, right? I mean it does exist. Is the underground city in Virginia a secret still? Its officially known as Mount Weather.
