Golf Ball: It's That White Thing With Dimples

摘要

The recent brouhaha over golfer Dustin Johnson's goof-up at the PGA Championship (a penalty that cost him a shot at making a playoff for the title) led us to hunt for the official rules of the game online. We found them at USGA.org, more or less. We say "more or less" because the U.S. Golf Association (USGA) actually only shares responsibility for the rules and interpretations of golf with the Royal and Ancient Golf Club of St. Andrews.
