Colt said that Swinley Forest was his least bad course or something along that line. I would think that Macdonald felt NGLA was his masterpiece. Did MacKenzie feel Cypress Point was his greatest effort? Ross and Pinehurst #2? What about other famous architects or not so famous architects (Tillie, Flynn, Simpson, Thompson, RTJ, Dye, Fazio, Nicklaus, Rees) -- what did they, or do they, consider their greatest single design?
