My friend and I were playing match play on the Par 4, 308 yard, 11th hole at Lebanon Valley Golf Course for our weekly summer 36-hole Monday match. Following a failed birdie putt that was part of a three-putt bogey on #10, I decided to take some aggression out and attempt to cut the #11 dogleg right with my 917 D2 driver. I normally play a 6-iron and wedge on this hole, but decided to get bold and go for it. The fairway on this hole slopes dramatically down to the green for the final 30 yards making this a blind shot from the tips. So, I picked out a visual line using a tree in the distance and smoked my tee shot in that general vicinity. Following my partner's errant tee shot and subsequent two shots to get the green, we began searching for my ball. He immediately thought he spotted it in the left cut of rough next to the green, but that turned out to be a goose feather. We then searched high and low, including going across a road to a residential front yard (this hole is on the perimeter of the course) only to find two balls hit O.B., neither of which had my markings on them. Finally, after an exhaustive search that yielded nothing, I told him, "Well, maybe it's in the cup." So, I walked down to the green and took a peek in . . . and there was my #2 Pro V1 with two purple dots in the bottom of the cup. I told him matter-of-factly, "Yep . . . there it is." At first, he didn't believe me. But, then he came over to see for himself . . . and then HE went crazy ("Oh my God, a hole in one!!!" . . . he was yelling). Meanwhile, I just kept looking downward at the ball . . . staring at what I realized was my first-ever ace . . . and it came on a par 4.
