I saw this guy in the azalea bed at #10 I think. I assume he's using a laser range finder get the distance of each player as they make their approach shot to the green. That information would then go into a useless pile of data for some number cruncher to devour. Or, he could be a lost surveyor trying to locate his partner, or a sneaky photographer with a fancy new colorful camera or finally an agent from homeland security getting the coordinates ready for a smart bomb to hit a terrorist in the head along the 10th fairway. I guess either way I'm cool with it.
