Tom Doak,
It has to be painful to see features you've created, softened, modified or eliminated.
I know that it would be painful to me.
Many green chairmen that I've spoken to remained upset for years when a feature they uncovered or restored was re-altered, and they weren't the original creator.
While your presence and prominence in the world of golf course architecture remains high, as time goes by and you become less active, less accessable to consult on courses you've designed, outsiders will be called in to pass upon the suggestions of the owners/members. They'll also be asked to make their own suggestions.
In addition, the internal erosion of the architectural integrity of your designs will begin to come under attack from within, subjecting alterations to the whims of the members and the latest architectural fads.
In my limited observations, these amendments to the golf course can be almost universally categorized as "dumbing down" the golf course, not improving it or adding more to the challenge.
CBM, SR, CB, Ross, AWT, Dr AM and others had their works altered/disfigured/destroyed so it's nothing new.
My question to them would be, if you had it to do over, what would you do to try to insure that your creations would be preserved rather than dumbed down, altered, disfigured or destroyed ?
I would ask you the same question.
And lastly, who's work has been altered the least over the years ?
Perhaps another trend will take hold, that of preserving rather than altering the Sand Hills, Pacific Dunes, Friar's Heads and Sebonacks of the world.
