Hmmm....interesting take, Jud. I am wondering if that is simply your personal assessment of the courses which may not be in-line with the golfing community as a whole.
True, Whistling Straits is ranked as the 3rd best modern course by Golfweek with Pacific Dunes #2; but there is a fairly significant point difference between the two.
Golf Mag ranks WS #24 in America and PD #10.
Golf Digest ranks WS #22 and PD #14.
Taking into consideration the Modern vs. Classical lists of GW, they might have it pretty darn close to right...as all three ranks PD just a bit better...but it appears WS is no slouch.
Concerning GW being "silly" ranking WS ahead of Kingsley. Perhaps, but Golf Mag and Golf Digest don't rank Kingsley in their Top 100 at all. So, it appears GW might be way ahead of the curve.
Again, it might be that you prefer Kingsley to WS (and maybe many of the participants of this site)...but that doesn't seem to be the consensus opinion of the golfing community.
