I was looking at an online article about NORAD and I got to thinking just what are some of the most restricted places out there? I used to work at Sequoyah Nuclear Plant and had to go through a background check and pass a certain status in order to maintain access to the areas I worked in the plant. Being in Communications our room and equipment was located in a very secure area of the plant, such that I don't know that I can even mention where it was today. I don't think it's classified or don't remember but I also don't want to take the chance of saying where it was, so I won't but it was a restricted area that not every employee in the plant could access.
That said some of the other places that I could think of was of course the White House, Air Force One, and places like Area 51 but one of the places that I think is the hardest to get access to, even for politicians or people in Washington, is Fort Knox, in Kentucky. I've heard that Fort Knox is one of the most difficult areas to gain access to for even Government officials and that has led to speculation that the Nation's Gold Reserves have been depleted and is no longer there. Anyway just curious what others think is the most secure place in the nation (I know there are many).
