Would be great if we one day knew about the exact layouts of these underground installations the top level roth and cabal members love so much.
Two places that even comes close, to my knowledge, are Site R (not so secret) and possibly someplace related to the ozarks that could have been used for this purpose. If the NWO families have facilities underground, I am sure it would be far more extensive and wide spread than these two, and Site R alone apparently takes a good half an hour to drive around in just to reach 50% of its layout.
True 'underground tunnels'.
