It’s funny, I watched this last night and am familiar with Hall’s story. Don’t necessarily buy it. But then again his recounting of them disguising themselves and roaming around Vegas can be verified by casual observation on any given night there.
The most interesting element of Hall’s story has not yet been discussed in this thread.
He claims the Tall Whites have had a base in the Nevada desert for hundreds of years—and the US military trespassed on their territory when they started building the bases in the area starting in the 1940s.
Old Indian “myths” of the region support his story.
