Ed,
It is a hypothesis. If I dub my tee shot into the native, chunk it out, into the fairway, top it into the fairway bunkers, get a plugged lie - take 3 shots to get out, hit my next shot fat, skull a wedge over the green into the crap, chip on and 3 putt, then I might not consider it a fun hole. I have no intent to debate what IS is or what fun is. Fun to me is to stand on this tee and visualize hitting great shots to the (personal preference) ideal spots, and when I get to the green make the putt. Hell, Fun to me is just looking at different courses. I do not necessarily have to play them to consider my experience fun. Golf is meant to be fun. I think Mr. Doak understands that. And that is my opinion.
As a near zero handicap I had fun tonight playing golf with my son. I shot a 48. Not bad for a near zero. Although the term Zero could mean different things to different people.
