I have one and it was more than 10 years ago. Playing a local course Fox Hollow and on the second hole, it was about 140 yards (no range finder back then).
It was windy so I hit a solid 9 iron and it landed right of the hole bounced once and then landed and turned straight left and into the hole. The green had a lip at the back so I thought it rolled off the back. My buddies were excited telling me it went in and I didn't believe them, I was sure it rolled off the back.
The 3rd tee is up a hill to the right of the green and the guys above us started going nuts. I was so shocked I actually got a hole in one I could only think to raise my arms up in the air lol.
