After 13 years of trying, I finally completed my own "Grand Slam." I've made aces on all four par 3's at my home club, Ironbridge Golf Club. This last one was hole 11, pin was 145 yards. I hit a cut T100 PW, it hopped once and disappeared. We all saw the hop, but it was behind a small mound so we didn't see it drop. Nothing like coming around the corner and... no ball near the pin. Walked up, and there was my personalized PROV1 sitting in the cup. To make things even better, I won the hole in one pot!!
