My son and I visited both gates last Friday, March 17th. During our ride, we noticed odd signs the size of mile markers on the Groom Lake side of the ET highway. The signs were a series of square dots and vertical lines arranged on either side of a single solid vertical line, and one each were just vertical dots (8 total) and two vertical lines. (I have pictures were haven't figured out how to post them here yet.)

Does anyone know what these signify? I've never seen them anywhere else. Google mentioned "Tacmars" but there isn't any resemblance to those examples.

Thanks in advance.
