Mac,
How do housing courses damage the game exactly? By putting golf in peoples backyards so they can play nearly every day they choose? By making it affordable as well as accessible?
I am not buying the fact that if there were no housing cousres, all 17,000 USA courses would be masterpieces. For that matter, I think there would be far less than 17,000 USA courses, and far fewer than 25,000,000 golfers, which would further impact the cost of all aspects of the game.
I think there is a great case to be made that while generally somewhat less quality than a stand alone course, overall, housing courses have helped the game.
I also think if GT felt that strongly about it, he might not have designed Bel Aire...among others. Nor would Mac have done Pasa, there would be no Pebble Beach and on and on.
