...but I just shot a 21.
A few "lucky" bounces and made all the shots I should make.
All hole in ones except the par 4's (2) and #13 which I have never been able to ace regularly.
I think 20 is the minimum possible - one can't hit the par 4's hard enough to get it to the hole, certainly not 8, maybe not 17 although that may be possible.
I think I will give it up now unless someone shoots 20 and I have to match it out of (yep) pride...
