Don't tell me there's something you're not good at?
Finishing on the 18th with a 68 isn't too bad, just a shame I started on the 10th. It may well have been my worst score ever for 9 holes. I used to think of 50 for 9 holes as being about par for me when I was playing a little more often.
I did shoot 79 for 18 holes once but the Maddington course was not particularly long or challenging, I think it was par 65 and that was being very generous.
My best ever was an 80 on the Pickering Brook golf course (my home club) par 72, a 41 on the front and 39 on the back. Surprisingly the 39 included a double bogey on the 10th so that shows how well the rest of that nine went!
