Tom Mac:
I suspect I may have given some mixed signals as well, though it wasn't intended, and judging individual merits of a bunker would give way too much license to redesign and as Mark Fine noted "if you give someone an inch, they will often take a mile", but that is why I said the entire course must be evaluated first.
Again, I agree that there are many instances where a MacKenzie, Thomas or any bunker, maybe, could look better over time, but more often than not, my position still aligns with Mark Fine where he states "if the original architect wanted the back left portion of the green hidden, wouldn't he have done that to begin with rather than wait till the sand built up to hide it?" Now all of this does begin to get into opinions, nothing wrong with that and I would love to know Bill Coore's and Tom Marzolf's positions on this issue, and semantics. Looking back in reflection, who is to say that the original work was in fact 'perfect' and exactly the way the architect wanted it, for as we know there were many architects who constantly went back and reworked much of their designs, so where does this leave us?
Maybe we should just agree not to call any of this work as "Restoration" for this seems to bring about way too many interpretations and it just feeds the controversy over is it or isn't it??
Tom P. might be totally right though and I mentioned this before. In the end, it is up to the club, no matter how good of a sales job we might do to guide them in one direction or another, even with the most diligent research and obvious conclusions. It is their club/course and they have to love it and accept it when they step on the first tee and walk off the eighteenth green each day. Yes, we can and do have our opinions, but all we can really do is present the information, with due diligence on our part and assist our clients to make good informed decisions.
