Gib,
I have never played golf to demonstrate my toughness or lack thereof. I play the game for enjoyment and nothing more.
If you haven't played The National, then you really don't know what I and others have tried to describe.
For me there is little joy in reaching a green in two shots, which in itself is no mean accomplishment, particularly at a place such as The National, and then be faced with the almost complete certainty of a three putt.
It is not uncommon to have a putt of 20 feet that requires 15 feet of borrow around one of the swales or slopes. If I want that kind of "fun" I can play a putt-putt course for an hour or so.
Harwood, like me on the day in question, was distressed from the heat and walking a very difficult course through sand hills and up some severe slopes.
I don't think Mike was trying to prove how tough he was, but I could say that he was equally as silly as me for walking it in such adverse conditions.
Why have I been back 10 times? I have friends there, and I believe to continually knock back invitations would in the long term cause offence. They believe, like Justin, that if I play it often enough, I will in time love they place as they do.
I think maybe not . . .
