RMD,
The Garden City Gimmee is either a myth or a well kept secret.
If anything, golf and tradition remain strong at GCGC.
I haven't seen anyone concede 6 footers at GCGC.
If anything, there's a tendency to "hole out"
I do agree with your take on the elimination of luck, vis a vis putting surfaces.
But, with rare exception, GCGC's greens are absent substantive contour, in favor of slope.
Tom Doak,
The greens at GCGC have gotten slower, not faster over the years since Bobby Ranum left.
It is true that they were sometimes preped beyond prudence for a few tournaments, but, as an overall trend, they've slowed down since Bobby's departure.
I suspect unusual weather and other factors conspired to tax the greens beyond sustainance.
