I have been a lifelong member of Humboldt Country Club, in Humboldt, Iowa. I was out playing golf late one evening and the #6 green sits right next to the #7 tee box. I was playing solo, but a high school classmate and his daughter were teeing off #7 as I hit my ProV1 up to the green. He told me that it took two hops and spun back to the hole and went right in. He and his daughter finished the round with me and I eagled the next hole, which was a par 5. Shot 31 on the round. Best round of 9 holes I've ever played (and had a double bogey earlier in the round).

A month later on the same hole, was playing with my brother-in-law. I hit a pure ProV1 and it approached in much the same way. We lost sight of the ball. I thought it had gone over the back of the green, but by BIL was sure that it went in. He was right! Waited my whole life for my first hole in one, and got my second within a month, almost to the day.
