I am advocate of Viollet-le-Duc's priniples: "it is better to consolidate than to repair, better to repair than to restore, better to restore than to rebuild, better to rebuild than to embellish."
Believe me, the well preserved (and sensatively restored ) NGLA of today (incuding modern sprinklers and modern maintenance techniques) is not a museum piece.
Tom like you I admire the restraint with which NGLA and other courses that continue to garner respect: consolidate, repair, restore and rebuild. But with every step they also loose something - that indescribable something. And this process by definition will not stop but must continue with time.
If this group were, for the sake of argument, to really put it's mind to it and agree another rating, a list of 100 important classics and define the year at which each course was in it's peak condition, would we then have a responsibility to argue for keeping those courses at this peak? NGLA is one of the top 10 (IMHO) of these courses, and yet you seem to be happy with it as a course today and as a course 5 years after Macdonald designed it. For a grade A example of what we are talking about both can't be valid, can they? Surely a top 10 on this list deserves scrupulous attention to detail, every effort expended to maintain it’s key values and an end to compromise and staying with the times?
What changes already made are acceptable and what changes in the future can not be, before too much is lost? In other disciplines the current thinking seems to me to be to restore using original methods back to, as near as we can identify, to the original, particularly for important examples of an art or craft.
I fully accept that NGLA today is no museum piece but I also believe she is not the same as seductress who challenged the golfers of 1914.
Is it important to look at what we've lost and how they’ve changed or just to celebrate that the old beauties still have charm? I just believe that with golf courses there’s no real chance of going back and there’s no future in trying to hold the fort. I think we agree on the need for sensitive development of courses but disagree on whether restoration is desirable or even possible with a golf course.
The questions in my mind remain, why would you want to resore and to what would you want to restore?
