Patrick,
"How can you see the contours, let alone the green, from a deep bunker?"
Umm, you take note of them before you enter?
I think we got lost in translation vis a vis Winged Foot and Oakmont. I wasn't querying whether they were deep, I was merely posing a rhetorical question, since I have never seen them, and asking for confirmation.
And there must be manufactured, and 'manufactured'. Why do so many architects get slammed for creating obviously artificial features, yet others past muster?
I have but no doubt, manufactured or not, that NGLA is a superior golf course, not least because yourself, TE PAul, Tom Doak, and, in "Golf From The Inside', where he says it would be at the top of his list to play, Mike Clayton, say it is.
