While playing last Sunday, I tied off on # 6, a 169 par 3 from the white ties. Using a png ISI copper 4 iron, I played my Titleist DT yellow from the elevated tee to the green below us. The ball hit the front center of the green, bounced once and rolled to the cup. We lost sight of the ball and my playing partner Dave said "I think it went in". He tied off and we headed towards the green. After looking for his ball, I walked to the cup and saw my TItleist at the bottom of the cup.
