The evolution over more than 130 years of this design is fascinating and has yielded what many consider to be the game’s finest front nine. Blind tee shots abound, in brilliant fashion at such holes as 2, 5 and 9. On the back side, one feature that was recently expunged was a natural pond 100 yards shy of the 17th green. Member George Combe deserves much of the credit for RCD as he shepherded the course through the transition to the rubber core Haskell ball 120 years ago. Forty percent of the World top 15 (here, Pine Valley, Oakmont, Royal Dornoch, Pebble Beach and Merion) derived much of their substance from individuals who built few other courses. Such designs enjoy their own unique voices with County Down further blessed with staggeringly handsome long views of the Irish Sea, the Mountains of Mourne and the red-brick steeple of the Slieve Donard Hotel.
