Charlie,
I actually like counter factual discussions, especially with material like WW2 strategy, e.g., what if Hitler didn’t invade Russia or Japan didn’t bomb Pearl Harbor?
But this counter factual loses me: not only was golf in Augusta first built on sand, but the architect Jones selected had already built on sand elsewhere and I have never heard anyone suggest Mackenzie thought the nursery was a bad site.
All that aside, it seems the United States was destined to become a big golf market and that most golf courses would NOT actually be built on sand. Would building the Augusta National Golf Club at the Bon Air site have changed that? I think not.
At best a counter factual argument would really focus on the influence of television on golf course maintenance and the so called “Augusta syndrome”.
