Playing with two customers and my co-worker we tee'd off early on May 18, 2016. It was a beautiful day as the fog had already burned off. We hired a four caddie, Chris Murray to assist us with the round. ironically Chris was my caddie for a round I had played a month earlier at Spy Glass with my son and wife. The golf round started off as every nomad round, idle chat on hole #1. I tee'd off first on the first 4 holes. I had just 3 putted hole number 4 and was re-playing my terrible putt in my head at the tee box on #5. I stuck my tee in the ground and was about to hit when I pulled the tee out of the ground and announced, "we are changing up the order, I will hit last!" My customers and co-workers stepped up and hit their shots. It was my turn again and I was vacillating between a 9 or 8 iron, and Chris yelled over to me empathically, "it's a 9 iron!" Then my co-worker added, "just step up and hit it" taking their advice, I grabbed a 9, walked up to the box, put my tee in the ground, squared up with no practice swings, and hit a solid shot. It took off my club and traveled in a high trajectory right towards the flag. The green was elevated so we could only see 2/3 of the flag stick. Chris yelled out, "that's going right at the pub!" Pause, waited 3 seconds...., Chris took off towards the green running the 130 yards in a split second. Then he slowed as he approached the green, he casually walked up to the hole lean over, paused a brief second and the. Lifted both hands like football referee! The Titleist PRO V1 landed 10 feet short of the pin and rolled into the cup. My first hole in one!, Spy Glass number 5, 130 yard, 9 iron.
