The following are the various ways we’ve all heard for many years and years. Be ready to play your shot, take only one practice swing , leave your cart or bag on the side of the green enroute to the next tee, putt out if you can, watch your ball , play the correct tees for your ability. HOWEVER , here is the one tip that will make everyone’s round more enjoyable and I read this on every water cooler years ago when I had the privilege of playing Shinnecock Hills Golf Club in Long Island New York. It read ,” Remember folks, your place on the course is immediately behind the game in front of you, not immediately in front of the game behind you”. In simple terms, stay up with the group in front of you !!!!!!
