Ok, I will not give where i obtain these(not a website) but ok:
-They test Cosmic Rays(time travel) in the Mountains near there and you are told not to look at the mountains.
-The convoy that comes in , has 18 wheeler trucks which could be carrying anything. The guard at the gate dosent check them or anything. They go directly to a hangar like area and do..stuff.
-There are hardly any people above ground. Most just troops are above ground, but there is like an underground type city there(kinda like Resident Evil) and it is just like a town with schools and things, But no people(awkward huh?)
- and last, every so often, there will be a staircase out in the desert area, it sits there for 2-3 days then just...disappears.
This sounds like an airplane exit staircase but it couldnt be due to the rocks in the desert.(UFO?)
Well, keep reading my posts for more secrets!

If that made sense I could form a proper reply.

what is this man talking about
