wsmorrison;
I find your report a little sad and quite ironic. After all, wasn't it the club's contention that several bunkers were "caving in" that led them to completely redesign the bunkers AND their surrounds in the first place, as opposed to just fixing drainage and other "infrastructure" issues?
If they are already having problems with the bunkers collapsing or becoming unstable, I feel badly for the club and hope they are able to easily correct the situation.
I played there the summer before the Fazio/Macdonald work began and to be honest, I didn't see any evidence of bunker collapse whatsoever, although I did note that some type of burrowing hornets had created a nest in the bunkers between 11 & 12.
In fact, at the time, the bunkers looked quite magnificent and those that had already been worked on and "restored" by another design group were simply out of this world in terms of look and playability.
In playing again last year, post Fazio/Macdonald, I also noted the change in depth that you mentioned, as well as the almost vertical, thick, bluegrass faces on many of them, which is something totally new and unlike ANYTHING I've seen from any Golden Age architect, anywhere. Similar to yourself, one in our group actually almost lost a ball in one of them on the first hole (we looked for several minutes) and nearly had to take an unplayable lie because his ball had lodged about 2.5 feet down on the thick, sheer, grass face.
