Gary D:
I have not made the list you want to see. If I ever do, I'll send you a copy. As for the bunker on the tenth at Riv, it angles away to the right, but the golfer senses on the tee that he can still carry it over there so he tries and does and then finds out that's not the right place to go. The best angle to play at, for most people, is over a portion of the bunker which blinds the fairway on the other side. It is subtle and clever and certainly not an accident.
Dan K:
Yes, absolutely we think about who is going to find certain bunkers, although you never can tell.
My first day of consulting at Garden City Golf Club many years ago, I was walking past a deep bunker on the left side of the fourth fairway, which is blind and marked by a flag so you can tell from the tee where it is. It's also a long way from the tee -- I couldn't tell whether it was 250 or 300 yards on that day -- so I asked my caddie if anyone ever drove into the bunker, and he replied yes, fairly often. With their tee shots on #5. (Which is about 75 yards off line.)
Bill V:
What exactly is an "unmaintainable" bunker? We sort of like it when our bunkers look naturalized, and when we have problems, it's usually because the management are trying to put a level of grooming on the bunkers which we had not intended.
