Drew and BH: overall flow of hole, direction (which means wind and sun) wide, tilted, hard-to-lag greens. Those are some of the connections I made.
And, the two holes both have trouble left, off the tee.
On 1, I hit a rotten approach, then pitched low left to a high right hole location. I looked at the putt and tried to figure out how I was going to map a route. Three putts later, opening double and away we go.
When I saw the approach to 18, I recalled my opening flubs and resolved to do better. My approach hit the green, my lag was better, and I made it home in two putts.
