A lake extends the full distance between tee and green. The pin was at the rear of the green. I struck a clean, straight 7 iron. My ball landed in the centre of the green, hopped forward once and trickled towards the hole. As it disappeared neither I nor my playing partners were sure whether the ball had dropped into the hole or rolled behind the pin. Having walked around the lake the ball was not visible and I was delighted to find it had gone into the hole! Celebration!
