I recently returned from playing in the Kansas Amateur in Garden City, Kansas. The tournament was played at Southwind Country Club, a Don Sechrest design in the southwest corner of the state which most would be surprised to learn is sand dune/desert landscape complete with ice plants, cacti, and rattle snakes. The 15th at Southwind is quite possibly the hardest par 5 in golf. Certainly harder than anything I've played.
564 yards double dog leg into the wind which during the summer is typically 10-20 miles per hour with gusts to 30. The tee shot is played from an elevated tee box to the southwest. The fairway is ample but from the left side your second shot is a blind shot over a hill to a narrow downhill fairway. The right side of the fairway provides a view of the fairway for the second shot, but errant tee shots too far right and through the fairway find severe side hill lie on a sand dune covered with the aforementioned ice plants, cacti, and an occasional rattlesnake. The second shot is played to the southeast down hill to an incredibly narrow fairway, 6 paces wide at its narrowest point. The rough is another six or seven paces and beyond that back into the sandy gunch. One may be tempted to go for the green in two but the right side of the green is guarded by a 65 foot thick gunch covered sand dune 30 yards in front of the green and the left by an expansive green side sand bunker with yucca plants (a la Prairie Dunes) on the green side margin of the bunker.
The third shot (from the 6 paces wide fairway if you hit it) is played back uphill to the southwest to the elevated green, an errant pitch shot to the left finds the aforementioned vegetation rich sand bunker and errant shot right the green past the sand dune finds a severely sloping rough covered hill running away from the green.
The green which is approximately 30-45 feet above the fairway is a long (front to back) narrow green with two levels, the front half is slightly dome shaped, the back tier, which is maybe fifty feet above the fairway is relatively flat.
Hardest damn par five I've ever seen.
