People,
Here is another Moon video from that guy who never mentions his name.
The last half is quite an eye opener.
But there is something that smacks of the underground, too. Be ready by the time you get to minute/second 16:21. Look at the smokestack (I guess) that the arrow points to. It is blowing out some smoke or gas that enters into a hole in the side of a sheer wall. Or, it is blowing out of the hole in the sheer wall and getting sucked into the huge pipe or whatever it is.
One thing is for sure; this is from underground to underground.
Comments are welcome on this one, I am still thinking about it all.
Cheers!
