Had been hitting the ball well Was even par up to hole 7. The tees were back and the pin was in the very back of the green. Hole is a little downhill. Just wanted to be in center of green. Measured yardage at 161 and thought a 7 iron would be the club. Hit shot and it was flying right for the hole. I bent down to pick up my tee and my playing partners started yelling. It went in hole. I did not see it go in. It was my first hole in one. I will be watching from now on. Shot one under that side. Fun day.
