This was the beginning of the end. None of your cylinders are firing and your opponents are ham and egging it extremely well. Mark and Matt played extremely well all day long and KLynch and I just never found "it."
To keep this GCA related, the Travis bunkers were all wall-enhanced by Ian and his team. They may have been that way in their original state, but they were flattened in the intervening years to allow easy egress. Ian and his team did not need to add extra yardage to return the course to its original Travisian difficulty; the augmented bunkering made each sandy pit a 1/2 stroke penalty, something that had been lacking since...forever.
RE: centerline bunkers on #7...you'll notice that they were already gone by the second aerial photo. I can guarantee that they haven't been there since 2000, when I first started coming to Cherry Hill for coaching. Ian made a healthy compromise. There was no way to remove the trees that have grown up 'twixt #7 and #8 fairways. Removing them would have eliminated the right-side tree hazard and allowed for centerline bunkers. By placing the new bunkers along the right edge, in the second shot landing area, he pushed play away from the trees, albeit toward an area with more rough. As Mark notes, it's a short par five. You can lay up well short of the bunkers and have short iron in for your third.
#8 is a tough hole. The drive is pinched by the sand and the water (which wasn't there in the original layout, but was added for aesthetics, irrigation or both) although the fairway is reasonably wide. The green is hidden a bit by the green-short fairway bunker, about 30 yards shy of the putting surface. Sand on the right of the green is found by weakly-executed shots from righties. If you miss the green left, you must recover "toward Buffalo," ensuring that your shot will run more than it should (sometimes into the sand.) Mark's birdie there was his best hole against par of the day.
