Patrick;
As much as he "designs" any number of his courses, I suppose.
From
www.mansionridge.com"Created by legendary golfer and world-renowned course architect Jack Nicklaus, Mansion Ridge is carved out of the mature forests and rolling hills of a 220-acre estate, and is the only Nicklaus Signature course open to the public in New York State. The spectacular 18-hole championship course features stunning rock formations, extreme elevation changes, and spectacular views of the surrounding countryside. Designed to test shot-making skills, this layout will challenge you to negotiate a variety of wetland areas, bunkers, and of course, all the subtle features you would expect from the Golden Bear."
"This 6,889-yard, par 72 course reflects Jack’s meticulous attention to detail and his demand for excellence. Jack’s signature means he walked every fairway, landing area and green to ensure that they meet his unyielding standards. As you play the course you can’t help but notice his influence, his personality, his drive for excellence, his touch … the touch of the Master."
See!! He's walked it...METICULOUSLY!
