From a source: (who also sent the bus video)
I saw these buses this weekend on a family trip. Several semis hauling Very Large white buses with no markings except a very small .gov sticker in the entrance door window. We drove up to the buses at the truck stop and the first driver wouldn’t talk to us just put his head down when my Mr. Man asked him questions. We circled around and talked to another driver who just said that “they were going to an undisclosed government location below Washington DC” My husband said to me, “did you notice those big compartments on top? That had to be for luggage” This is very close to what we saw, except racks in front and huge compartment on top, storage air systems??
We are so much farther along on this road than people realize.
