I was playing golf with my 2 sons, Mark and Matthew and my son's friend, John. It was a friendly match between Mark and I vs. Matthew and John. On the 10th hole at Ridgemont Country Club in Rochester, NY on Thursday, September 24, 2020, my son Mark Metzler got his first hole in one. It was a 171 yard shot and Mark used a Titleist PRO V1 golf ball and a Titleist CB 704, 4 iron. It not only was Mark's first hole in one, but was the first hole in one I witnessed where I was actually playing in the foursome. While Mark was extremely excited and happy, I believe myself, my son Matthew, and Matthew's friend John may have been even more excited. Unfortunately, that was the highlight of our match between Mark and I vs. Matthew and John, since they ended up beating us. A very exciting moment!
