4. Area 51
The famed stories be true or not, this area in the remote deserts of Las Vegas is more than just strange. It is also one of the most secure locations on the planet. It is a United States military base ( a detachment from Edwards Air Force Base in CA) where no one knows what’s occurring, except those that work there and the President. Known by many names (Groom Lake, Dreamland, Paradise Ranch, etc.) Area 51 is believed to be a testing ground for advanced and experimental aircraft.
