Have to add a few nods to those who mentioned the following:
The fairway bunker on #8 at Wild Horse. Great stuff indeed. It reminds me of the Bermuda Triangle -- you go in and you may not get out!
Have to also mention the cross bunker at the par-5 4th at BB as well as the front bunker at the long par-4 15th. Two great holes that finally came to public attention during the '02 Open and the bunkers onb oth are simply awesome stuff.
Have to also mention that tweeny weeny fairway bunker on the 2nd at Rustic Canyon. Tommy N mentioned it to me when I played the RC for the first time back in November and I was dam fortunate I didn't get sucked into it!
