I walked the course with DMK a few months back and was very impressed. The 17th is indeed a heroic hole. I told DMK that it reminded me of the 14th ("Calamity Corner") at Royal Portrush, which amused him since his guys have dubbed the recessed chipping area back left of the green as 'Bobby Locke's Hollow' (Locke got up & down from the hollow in front of the 14th at RP all four rounds of the 1951 Open).
