Neil -
You gotta hand it to RTJ. To get this sort of publicity about his gca ideas in the darkest days of WWII is impressive.
Bob Jones hired RTJ to do Peachtree and make changes at ANGC on the strength of his belief that RTJ understood MacK's design philosophy. There is no way to know if Bob Jones ever read this article, but I recall RTJ saying similar things in golf magazines in the late 30's, usually also mentioning his partnership with Stanley Thompson, who actually knew MacK.
(Not to go off topic, but I've always thought the interesting question is not why Bob Jones hired RTJ in the late 40's, but why he never used RTJ again.)
Note that Herb Strong's Ponte Vedra and Flynn's Indian Creek are mentioned as "masterpieces" alongside NGLA, Lido and others. I am not familiar with Spring Hill.
Great find.
Bob
P.S. I've never understood why it was important that you couldn't see bunkers looking back from the green to the tee. Why is that supposed to be a virtue? Isn't it just a function of bunkers having lips? Some do, some don't, but that doesn't say much about their quality or the quality of the hole.
