Playing with my friends on sunset course at Underwood golf club, are 3 number 144 yd into the wind, I had a 7 iron that landed on the green and just disappeared. We thought it had rolled off and when we got there there was no ball anywhere to be found except at the bottom of the cup. We took a picture come on we didn't yell or scream, I put a peg in the whole, and not only one the greenie but also the skin. Very good round of golf after that. 7 iron AP1 and yellow truck soft.
