The other day the course I went to was full and had no tee times available. I know the course really well, so I just got a scorecard and went to the range and played each shot in my head as if I was on the course, then I went to the chipping green and finished up each hole. I wasn't sure if it should count towards my handicap but I ended up with the best score I've ever shot, so I went ahead and counted it.
HAH got me in stitches. Let's not take this in the direction of the "How big is your drive" thread by TourPro.
