GPS Coordinates.
“”With the current regime, it’s a two word answer:
GPS Coordinates.””
Last year a Gov’t worker(pre census he said) showed up at my remote home with a GPS system to take a reading for my home location for gov’t records. He said he wanted to get the coordinates by my front door. He took one look at my German Shepherd barking and throwing a fit right beside the door, and said the coordinates from the car are close enough!
The equipment and plans for the collection of GPS coordinates was all developed and purchased during the George W. Bush Administration.
