During a recent round I noticed bunkers on consecutive holes where the surrounding vegetation could have a significant influence on play. The first was a greenside bunker with birch trees all along the back. Their branches hung down so low that a shot from the front of the bunker required trajectory control to not hit the branches. On the next hole was a fairway bunker with a large bush that hung down over the bunker. One of our group hit it in there and had no chance to take much of a swing at the ball.
Is this good design to make bunkers more of a true hazard, or should a well-designed bunker generally be hazard enough? What are some examples of vegetation infringing on a bunker's "personal space" that work well? What are examples of bunkers most in need of bush/tree removal?
I appreciate your thoughts.
