Jay,
I think I can add the entire back nine at Pasatiempo as my arch nemesis. It did it again to me today. I turned in 40, not great, but certainly not bad for me, and get to the back nine and its like I have never taken it back before. Hit the fairway on 10, hit it in the bunker up against a lip, have to play backwards, make a number. Hit the cart path with my tee shot on 12, can't find my ball. Another big number. Three putt on 16 (standard), three putt on 18 (standard). Doesn't seem to matter what I shoot on the front, I get on that back nine, all bets are off. I have turned in as low as 37, and never broken 80 out there. It does it to me every time. Absolutely love the golf course, and think the back nine is better than the front, even though I can't play it well. I joked that I feel like Sergio at Augusta, maybe the course is just too hard for me.
