The Texas plate does confuse. But looking at the mountains in one direction, open desert in another direction, gliders on airport and some what appeared to be helicopter hulks? But look at the video section with runway 2-20 and 10-28 where 20 and 28 are in the same intersection along taxiway A.

My guess is Inyokern, CA. IYK, but it's just a guess.
