I was fortunate enough to play Spring Brook on several occasions while working in the New Jersey Section during the late 90's. The golf course was always in superb condition and the layout unique. Other than minor restoration or "facelifts", I don't imagine there was a need for any major changes.
My experience has found that people in important roles (Greens Chairmen, Club Presidents, etc.) usually try and "make their mark" by proposing something drastic be done to either a golf course or clubhouse so they may go down in history as the greatest member, club president, greens chairman or architect that ever lived. Architects definitely follow this pattern as they need to be noticed and recognized among their peers. There certainly are Greens Chairman who are experienced and qualified enough to take an active role in golf course projects. It amazes me that top clubs with excellent golf courses allow uneducated golfers, who play on a social/business level two or three days a week, to act as a golf course restoration/rennovation expert.
I look forward to an opportunity to visit Spring Brook in the near future.
