So the day started off with my friend and I teeing off on the back 9. At the turn to start the front 9, I hit one straight left, as I was looking for my ball I found a “cally triple track” I finished the hole with the cally. Now comes the par 3. My buddy goes first landing his ball 6-8 feet pin high. Now I’m up, I decided to use the “cally triple track” that I found. I hit the ball slight right. It had a good bounce off of green side mound. Then it started to roll towards the pin then It disappeared. I said “ it went in. A HOLE IN ONE, A HOLE ONE” my friend didn’t believe me at first. As we get up to the green there was only one ball to be found. So I looked in cup and there it was, My friend finished with a par. Told me not to use that ball any more. “ it has fulfilled its life, it was lost, it was found, it got a hole in one”.
