Pat:
Read your initial post again and as you do, particularly the part about external green features taking over for internal contours to challenge both approaching, recoverying, even putting---just keep thinking ANGC, ANGC, ANGC!
The way that golf course was designed (and mostly still is) could be one of the most remarkably breakthroughs in all golf architectural philosophy and concept.
The course was designed and built with 22 bunkers!! Are you kidding me? That's little more than one bunker a hole.
It's all about green shape, internal green contours, green surface slope and mostly short grass around the greens that the greens bleed off into with slope. Approaches can stay on some greens but be in places that two-putting isn't likely or they can slip off the greens onto short grass where recoverying to certain pins isn't likely either.
What could be more strategic and simplistically sublme than that? That concept and philosophy can go with a real minimum of bunkers, and it does not need narrowness of fairways, it does not need rough, and it does not need trees to work strategically and challenging.
Bob Crosby is still doing his research on that course and I think he feels it just may've been one of the real breakthrough concepts and strategic philosophies ever conceived of and tried. I'm very much beginning to believe him on that. But the ironies are---apparently that breakthrough concept and philosophy was largely misunderstood and is getting more so as time goes by.
