Heard, Not Seen

I was playing in the Member-Guest Tournament at the Elmira Country Club in Elmira, NY. Hole number 4 is an up-hill par 4 playing about 120 yards that day. I hit a perfect PW but because the hole is above the tee box, you cannot see your ball on the green. I saw the first hop and then heard the sound of the ball hitting the pin. I thought it had a good chance of being in. When I got up to the green, it was in the hole.
