Well, I hope George keeps it up for all 18 at Oakmont. Here's why:
Those of us (like, me) who have never played the course, and never will, and care about golf architecture, find much of this stuff pretty interesting. I like the descriptions, the photos, the discussions about how best to play the holes, and some of the evolution of these holes.
It's particularly relevant, given that it's hosting the US Open this year. It's really, really neat, because Oakmont -- beyond that of probably every single other major-worthy course in the country -- embarked on a fairly radical tree-removal project that most courses probably wouldn't have the guts to even discuss (like, Winged Foot or Oak Hill), and did so with the intent of presenting its course as nearly as possible to its original state, as envisoned by Fownes, in preparation for the Open.
In and of itself, that's a pretty cool thing. To have George on-hand to describe that process, hole by hole, and have others weigh in, is something to grateful about.
