Donnie,
I was thinking of a related topic just last night, the sectioning of a green into quadrants or shelves and plateaus.
I think they are a thing of the past.
A few people will cite an occassional green or course where they've been built, such as # 1, # 7 and # 9 at Friar's Head, but, in general, they are antiquated.
When's the last time you saw a new green like # 1 at Westhampton ?
The evidence that there're becoming things of the past is the existance of the trend to flatten existing greens that contain contours, plateaus and shelves.
OWNERS and Architects have forgotten that the interest and intrique in golf is largely centered in or around the green.
How creative can you get with a TEE ?
The trend to remove the character, the playing challenge from contoured greens as a result of increased speeds has diminished the desire to build new greens with shelves and plateaus.
And, because of this, purists, lovers of the game, will always love the NGLA's of the world, the courses designed by CBM, SR and CB.
