The fewest bunkers I've done on any course is 40 at Quail Crossing in Indiana -- on clay soils and a modest maintenance budget. I think half of them are on the last three or four holes. But there are plenty of wild greens to make up for it.
Tom,
I played Quail Crossing for the first time about ten days ago (and enjoyed it!), and did notice the economy of bunkers--there are several very good holes with no bunkers or just one.
But I am just wondering what greens you would consider "wild". I really liked the 7th and especially the 8th, and thought the 15th, 16th and 18th were excellent as well, but I didn't walk away feeling that any of them were overly bold--certainly interesting, but not wild.
But part of that may be the speed that they were the day I played them, and the fact that the greens at Victoria National (which I played under tournament conditions) were much faster...
P.S.--I would call the 6th and 10th greens at VNGC "wild", probably the wildest I've seen Fazio do--I was pleasantly surprised.
