JES,
Forget about length and strategy.....How could a gca see his course changing from a big time private club to a city run muni and all the effects that change would have on the design?
I think Seminole is about the same course it always was - a good CC test. In the old days, pre sand wedge, and with older equipment, the wind and bunkers might have been the biggest challenge.
Now, its the lightning fast greens and for many, still the bunkers - once presumably more in play for good players, now they affect far more average golfers.
A course with good bones will always be a good course. Figuring how all the possible changes of the future might affect it is well beyond my knowledge level!
