Joe,
What I find fascinating about those schematics is that the course appears far more difficult, far more penal in those sketches than it plays today, yet, we've had close to a century in improvements in equipment. If anything, you would have thought that the course would become more difficult as equipment improved.
Unfortunately, it seems to have gone the other way.
Tom Doak,
I always wondered about that area short of the green on # 8.
Also, look at the 9th green and how it contains similarities to the 12th green.
