CASTLE ROCK — It was 1979, and golf legend Jack Nicklaus was walking the property that would eventually become Castle Pines Golf Club with its founder, Jack Vickers. Gazing about the rocky, forested tableland, Nicklaus tried to wrap his head around Vickers’ vision of a championship-level golf course on such unforgiving terrain. “We went out and walked around the (grounds), and I said, ‘You really want to put a golf course here?'” Nicklaus recalled with a laugh.
