When I first went golfing back when I was about 13 I believe I scored 50 through the first 4 holes. My dad decided that after that we should just quit keeping score. So for the rest of the day it was just batting balls into the air and practicing my golf cart driving skills. Of course, even to this day I sometimes have a bad day and we just scrap the score cards and play some good old non-competetive golf.
Let me put it this way, I have had games where I don't either bother keeping score cause I would be 6 over every hole if I did. I am a terrible golfer and know it, no reason to keep a score to show that fact to my face.
You could keep the score, so when you become a professional golfer you can sell the scorecard of your worst game on ebay. No one will think it's possible you got 6 over par on every hole and bid like crazy..
But remember, thats if you do become professional, lol.
