I was watching the Steven Spielberg 1977 classic, Close Encounters of the Third Kind, with the family last night and nerded out when I saw a character that claimed to be a cartographer. I always do. It was the cartographer who recognized that the signals the aliens sent were coordinates. This is how they knew to set up camp at Devil’s Tower in Wyoming. But…do the coordinates really point there? Not really. Speaking of nerding out, allow me to nerd out on coordinates for a minute or so…
