Bunkers to challenge on the inside of a dogleg where the mowing lines allow rough to extend well beyond the backside on the carry line. As a matter of fact, I think this situation had its own thread on here somewhat recently.
This spring I played RTJ Sr.'s Otter Creek in Columbus, IN. Nearly every dogleg had a bunker on the inside of the elbow, and numerous times I thought I hit a perfect drive directly over the bunker or even its inside edge. Time and time again I would walk up the fairway expecting to see a ball only to find it caught up in rough well beyond the backslope of the bunker...
Now, I'm not always for fairness on the golf course, but when a bunker is set at a location and a distance that says "challenge me", I think there should be some sort of reward for executing the shot.
