Chambers Bay. I did the 72 holes at Bandon back in April, but I haven't been able to do more than 27 at Chambers. I often think about it, but every time I get to the green on 18, I realize I've got nothing left in the tank. Three big hill climbs at 4, 7, and 12/13. What you don't realize is the elevation gain on 8/9tee and 18...until you catch your breath.
