Very uncharacteristically, I've played twice in the past week, and will play again this weekend. If I play three rounds in a year these days it's a lot.
Yesterday, I played probably the nicest course in this area (Caves Valley CC) at a corporate shindig; got to play 2.5 holes with Zach Johnson. Pretty amazing to see how the ball just explodes when a pro hits it, great flight, almost boring though in its simple consistency. Two of our holes were driver holes, I bombed my first one right down the middle, pretty much a 98th %ile drive for me, and then he took a shortcut over the bunker that probably would have been in play for him were we not playing the whites and ended up probably 30 yards ahead of me. The next hole I hit another great one, miraculously again in the middle of the fairway, and he outdrove me by another 20 yards again.
It was a different story on the third hole we played (he only teed off with our group there, then waited on the tee box for the next group), a 185-yard par 3 he hit to about 8 feet. I hit so far left I even missed the bunker.
He was a very, very nice guy. Personable and fun.
This weekend I will probably play an executive course in my in-law's retiree-heavy community. It will probably be the biggest delta between quality of courses played consecutively you could achieve.
