Kirk,
The ironic thing is that by this point, thousands of clubs were that "stupid and arrogant", as they had all built courses by 1910 without the use of Charlie and Whigham.
Men like Herbert Leeds, and Walter Travis, and George Crump and Devereux Emmett and George Thomas and AW Tillinghast and countless others were all that arrogant and stupid, apparently.
In fact, although NGLA was a masterpiece that he worked on for many, many years, in 1910 it was really just starting to take shape.
His earlier effort at Chicago was horrendous.
He had the benefit of having come from Scotland, but so did countless others who came to these shores, mostly professionals like Willie Park and Willie Dunn. He had a brilliant idea that he was able to execute wonderfully at NGLA with the tremendous help of Emmett and Raynor, and for intents and purposes, it could very rightfully be argued that Emmett was really the guy there who knew his architecture.
But, in 1910, Macdonald was just learning as well, although he certainly was stupendous at trumpeting his knowledge and his accomplishments in all of the press.
Funny how he never mentioned that Merion routing though...
Perhaps he was trying to follow my mother's wise dictate, which says, "don't brag about yourself..let other people do it for you."
Of course, nobody else mentioned his Merion routing then either, though.
A rational person might say that it never existed, but hey...what do we know?
