Almost three years ago, Spencer Sappington was walking past the driving range at Crystal Falls Country Club in Dawsonville on a July afternoon when he heard a crack. The 2008 inductee into the Georgia Golf Hall of Fame can explain that the sound is the golf ball compressing from the forceful impact of the club. The ball doesn’t actually crack, of course, but the sound creates the allusion that it does, and it’s a rare sound to hear, the 74-year-old says, the sign of a smooth and true golf swing.
