At hope #3 at Sienna Golf Club in Missouri City TX during our Senior Men's Golf Association monthly tournament i was between clubs. I used the longer club, 8 iron, and choke up a little. When I struck the ball it took off directly at the hole. We all saw it headed to the hole but could not see the landing due to the sun's rays from behind the green making a reflection on the morning dew that had not burned off yet. The other players took their shots and when we got to the green my ball was not on. I thought I was possibly short of the green as I taken a softer stroke, but the other guys walked up to the hole to confirm it was in the hole. Not only did I get a hole in one, I also took the prize money for closest to the pin for the hole!
