2. The vault of Coca Cola
In Atlanta, at the World of Coca-Cola, you can have fun and you have access to pretty much everywhere except for the vault. While for the obvious reasons people aren’t allowed to usually get in a vault, here you are forbidden to pass because of the recipe of the beverage that sits in the vault.
It’s very well protected and you don’t stand a chance against the security installed in the place, just in case you were planning something.
3. The United States Bullion Depository at Fort Knox
Even though Fort Knox is completely functional and accessible, the Bullion Depository was only opened to the public twice. Once in 1947 and once in 2017. That may seem a bit drastic if the U.S. gold stash wouldn’t have been put in there.
4. The Bohemian Grove
The Bohemian Grove is a private and exclusive club for the most powerful men in the U.S. The property has over 3,000 acres and outlets have reported that during July, for two weeks, its members reunite.
It is unknown what they’re doing at the retreat during those weeks and what is actually happening at the club. If you wish to join the organization, among other requirements you have to wait for an average of 33 years to join.
