Tom MacWood,
Ross tinkered with Pinehurst # 2 for 26 years.
CBM did the same at NGLA.
Pete Dye has done the same at Crooked Stick.
But, somehow, I view fine tuning in a different light from modernization.
To me, fine tuning implies subtle architectural improvements, whereas modernization conveys an alteration to catch up wtih the quantum leaps made through technology, almost solely in the context of distance.
I was fortunate enough to talk to Pete Dye as he was in the process of tinkering/altering the 14th hole at Crooked Stick prior to the PGA. He had previously tinkered/rerouted the creek and was building a new tee further back and at a more cumbersome angle. When I asked him why he was making this particular alteration, he asked me, when I play Winged Foot, Baltusrol, Shinnecock and other courses if I hit my two and three irons into any greens. I responded, yes. He said, well so are these guys, (PGA Tour Pros) on this hole.
He then went on to explain the angle off the tee that he wanted to achieve that would leave them with a 2-3 iron into a green that would be difficult for them to get to the cupped quadrant.
Pete was also asked to design and build PGA West as a supreme challenge to the PGA Tour Pros.
His stadium course in Florida was altered a number of times and came under heavy fire from the Tour pros for an extended period of time.
There seemed to be a rivalry between Pete and the Tour Pros for some time, perhaps even today, so, Alice's comments may be in the context of keeping one step ahead of the greatest golfers in the world, and not necessarily in the context of country club golf.
I doubt she would advocate modernizing Prestwick, NGLA, Maidstone and other courses, but, I'd have to read the book and probably have a conversation with her before I understood exactly what she was trying to say.
