18. While relaxing poolside one Sunday afternoon, Dickie was struck by a golf ball driven by Marty, a 14-year-old boy, who was playing the 9th hole at the Pike Creek Golf Club. The fairway for the 9th hole was 65 feet wide and 437 yards long, with a dog-leg in an easterly direction. Between the fairway and Dickie’s property was a “rough” containing brush and low lying trees. As Marty was approaching the green, he hit a towering shot which deflected off a tree, struck Dickie, bounced off his head and knocked a straw hat off of his girlfriend Patty’s head.
