The bumpers at Rye.
I am probably in a distinct minority here, but I enjoyed the eyebrows on Kidd's Tehterow. These sage and lava hazards were surely small, cheap to produce, easy to maintain, and frustrated more golfers than can be counted. The equal of pot bunkers as they each extract one stroke. Smaller cousin of the island in the 5th fairway at Bandon Dunes, it seems to me they drew the most wrath from insecure golfers, or at least those who sought fairness in all the wrong places
