Area 51 – Lincoln County, Nevada
This military base has no aliens, but Area 51 has attracted tremendous attention from both conspiracy theorists and historians. If you try to enter the Nevada desert, you’ll find yourself before a fence, a stop sign, and two intimidating warning signs. There’s a range of surveillance cameras to stop you just before you reach the base. But what goes on at Area 51? The U.S Airforce uses the place to create or experiment aircraft, stealth technology, and new weapons.
Coca-Cola Vault – Atlanta, Georgia
In comparison to Area 51 and the deceased JFK, the formulation of Coca-Cola is America’s most elusive. It’s probably just a marketing campaign to make coke look even more unique, but only two Coca-Cola managers know the secret, and they know each other’s half. Sadly, there is no proof, as a handful of employees were probably familiar with this entire process.
