Nevada Test Site, Nevada

The claim: None, it's just listed a possible site.

What it really is: Now called the Nevada National Security Site, it was established in 1951 by President Harry Truman as a place to test nuclear weapons, and was used as recently as December 7, 2012 to conduct nuclear tests (be it underground and not an explosive type).

The site is also open to monthly tours to the public as well.

Due to the fact that there is a lack information on this alleged FEMA camp site, and the fact that it is open to the public, it just seems highly unlikely that a FEMA camp would be located here.
