#8 Fort Knox, Kentucky
Trying to get in here is like, well, gaining entry into Fort Knox!
This is where the phrase “Fort Knox” was coined. It’s not surprising, though, because this Kentucky building is so well-guarded that you have a far better chance than winning the lottery - twice- than getting in here.
This is where you will find the US bullion is stored as well as many other valuable national treasures. Fort Knox is guarded by a troop of 30,000 soldiers, attack helicopters at the ready and an impenetrable perimeter wall. The vault itself is blast-proof and can only be opened by a chosen few.
