"I am, of course, aware that many golfers feel that when they play a shot to a green that nothing in the way of a mound or swales should interfere with a seemingly well-placed shot. May I suggest such mounds and swales are developed to create variety in the playing of shots and that such variety adds, not detracts, from the pleasure in playing the game." — A.V. Macan (1882-1964), Shaughnessy's Golf Architect
