One round, about 5-6 years ago--shot 95 or so as a 9 or 10 handicap.
Made an 18 on #11 after driving into the Strath Bunker, and having something of an out-of-body experience over the next 60 or 90 seconds, whack-whack-whacking the ball time and again from the sand directly into the sod wall of the bunker. If I had blasted out sideways or even backwards initially, I guess I would have shaved a dozen strokes or more...
But I rolled in a 40--foot triple breaker on the next, so the scorecard read 18-3 on those two holes...
