Playing in my employer's covid golf tournament working on a new grip, I used a PW on the 181 yard par three third hole at Pocono Manor Golf Course in Pocono Manor, PA. It was a blind hole in which you were targeting hitting it about 150 yards then allowing it to run downhill to hole. I caught it pretty good so feared it was long but was told it took a nice kick right. When I went down the steps to get to lower level of green I could not see my ball on the green or past the hole so casually took a peek in the cup to notice my Titleist Pro V1 with markings I had put on it sitting in the bottom of the cup. Unfortunately my twin brother also hit a nice shot and was looking for his ball and when I yelled "Hole in One" I neglected to mention it was my ball rather than his. At least he had the feeling of his first hole in one even if it was short lived.
