Golf

I am spending 5 days at the TPC Boston (Norton, Mass.) for the Deutsche Bank tournament. Thursday, during the Pro-Am, I got training on the greenside laser. This is the view you get from up in the tower. Some are even better.
The laser is GPS positioned to shoot the ball locations and distances from the hole. It's accurate to the inch !
This info is uplinked to their website and also made available to the TV announcers (If you ever wondered how they knew).
