Pat:
I agree with Kelly. Why do you think deeper bunkers should be considered a liability issue today? Do you think some pathetic yahoo is going to get vertigo on the top of some deep bunkers, lose consciousness and topple into the bunker and hurt himself?
You should begin to think more like George Crump did when some hacker he was playing with at PVGC said to him;
"George, why in the name of common sense did you build these bunkers so high? If I fall off here, I'll break my neck."
To which Crump responded:
"Now you've got it. We build them so high that dub golfers would all break their necks. This is a course for champions, and they never get into trouble."
