"In my recent reading of some of the classic architecture books I have read an idea that "hazard" can be expanded to include hills, for example."
Of course topography (hills, valleys, mounds, depressions, etc) are used as strategic components of golf courses. Call them hazards if you want, but this obvious fact has been evident since golf courses were laid out on links and designed elsewhere. This should not be something recently realized.
"Would these guys be more imaginative and say "Let's use what we have here and make something out of it?""
Mike,
Who are "these guys" that you refer to? If the "what we have here" is cartpaths, then I'd say not on a classic era course which was designed without cartpaths in mind. Rolling Green has enough natural interest that cartpaths, a modern convenience, are far from necessary and would be a huge mistake to include strategically. You're thinking too much and not very well if you are exploring this area. Many cartpaths are in the wrong spot or not needed. Again, follow an integrated approach and let the experts lead. You follow their lead. Your in good hands with Forse and Nagle.
