mulegolf I've played in a lot of tournaments in the past years and never before seeing your post have I seen or heard of another golfer using green. I like it.
Most sharpie packs contain red, black and blue. I have a funny story. I put two green dots in the dimples above the ball name on both sides. I was playing years ago on a muni and had my green marks on my ball. I sprayed my drive in the right rough. I find it and getting ready to hit a guy is walking up yelling and waving for me to make sure it was my ball since he hit one there also going the other way in the same rough. I told him it was a Topflite Freak with two green dots and he said that's what he was hitting. We look around more and find another one about 15 yards away. Come to find out he was a few holes behind us and he had found a ball I lost on the front nine and had put it in play, so both balls were identical except for the numbers. What is the probability of that happening? 😛
