Not sure I can pick just one. So here is my best drive, approach, and putt.
A 330 yard par 4 at La Cantara (San Antonio). Wind was helping, but I swung out of my feet. Hit a nice fade and rolled up on the green and stayed there.
After a drive that landed in a heavy tree area well below the fairway and greens, I hit a PW from 125 yards away, I missed all trees and got it on the green. It rolled up and hit the pin. Tap in for birdie.
Best putt, has to go to my first birdie. Good drive, ok approach shot that just rolled off the front of the green. What was left was a 45ish foot putt, off the fringe, up hill all the way with 2 breaks. Sunk it and cheered estatically.
