Seems to me that this will all require a conditioning of GOLFERS, conditioning golfers to not require lush green Augusta like courses. Which course will be the first to risk letting their turf go brown in exchange for a higher GD ranking? Will golfers tolerate browner turf, or will they just complain? My guess is that golfers will keep requiring green and lush conditions, along with soft but fast greens, and will choose to take their dollars elsewhere if they see firm, fast and browner courses.
Just a guess, but this will require a long term reconditioning of the mind of the golfer (probably only occuring when water use is regulated on a wider basis), and an annual issue of Golf Digest ratings ain't gonna change much short term.
