Golf etiquette has been in the news lately, with everyone from Hunter Mahan to Tim McCarver (yes, the baseball announcer) weighing in on how the game should be played, and Golf Channel’s Brandel Chamblee opining that Tiger Woods might have played a little fast and loose with the Rules this year. Tiger’s agent is threatening legal action, but it could be worse: A Reno man pleaded guilty to wounding a golfer with a shotgun. Seems the golfer broke a window in the man’s house with an errant shot, and then, while taking a drop on the 16th hole of Lakeridge Golf Course, he was shot at, sustaining minor injuries. The shooter could get up to 10 years in jail and a $10,000 fine. And in Vietnam, a government official beat a caddie unconscious after being told that his shot missed the 13th hole at Tam Dao Golf Course near Hanoi. The official was banned from golf for a year. Sounds like The Rules of Golf might need some updating.
