Was playing in the Yokota Air Base's Tama Hills Golf Club Championship on 20 Sep '14. We reached the 7th to find the closest to the pin marker pretty close to the flag. The flag was tucked in the front right of the green, 171 yards away, I hit a 6-iron. The Pro-V1, custom #17, landed on the edge of the green, took a small bounce before rolling past the CTP marker and into the cup. There was a bunch of cheering as the group ahead of us were watching, as well as an additional group waiting with us at the tee box. Kinda of cool to write on the CTP marker, "hole-in-one" next to my name. The bonus was winning a box of Pro-V1s for the CTP competition.
