Barking Sands Pacific Missile Range Facility, Hawaii

The claim: Kauai, 1,925

What it really is: The Pacific Missile Range Facility, Barking Sands, is a Navy facility that is also the world's largest instrumented, multi-dimensional testing and training missile range.

While it's location along the coast makes it ideal for missile testing, the fact that it's next to sugar cane fields (which could be accessed by the public), and in is on flat land, would make it very hard location to hide a FEMA camp on.
