These are great stories to read. Here are mine:
1. Shot 64 (-7), which at the time was the course record, in the first round of the Cincinnati Metropolitan Championship just after my freshman year of college. I had broken in a tournament for the first time about a month prior in a college tournament. I started the day with three birdies and six one putts. I birdied three of the par 3s, two of them from inside a foot. I was -7 through 14 holes and heard someone following the group say he might shoot the course record. My dad was caddieing and told them to be quite. I hit inside 10 feet twice in the last four holes but lagged the putts because I didn't want to make a bogey. For the day I made 7 birdies and 11 pars.
2. The same summer as above I played in the Southeastern Am. I parred the first 17 holes. On 18 I hit it to 20 feet. I was playing with Nicklaus' youngest son and as we walked to the green he said "Don't worry if you miss this because you will have done something you will probably never do again." I missed the putt and finished the round with 18 pars.
3. At my club's member-member I shot 65 (-7), which is still the course record I think, the second day to bring our team back from the middle of the pack to second place by less than half a shot (they didn't round off the handicaps). And, I missed a 3-footer for birdie on the 5th hole that would have won it for us. My partner and I split $1,800 bucks that day.
4. Two years ago I shot 64 (-7) at my new home club, missing the course record by 1. I made 5 straight 3s in the middle of the round. And, if you saw those holes (which I typically play +2 to +4) you'd be quite impressed.
5. Had a four round stretch two years ago that was 66, 67, 68, 67. If Shivas could have putter for me one of the 67s would have been 63 or so. I didn't think I would ever shoot over par again.
6. Shot -2 from the tips at Spyglass when it was revealed on the third tee that one of caddies bet my caddy lunch that I wouldn't break 80.
