Great thread and admirable cause, Tom. You are incorrect, however when you write:
"Though history records that bunkers have been moved on The Old Course in past ages, no new bunker has been added and no bunker has been moved since 1920 -- and those changes were made after great debate among the members of the club, who included some of the leading minds on golf course design."
In fact, the Road Hole Bunker was moved (and significantly re-shaped) as recently as 2010 and there was no "great debate" on this event except for a bit of hand-wringing on this wee website. As I wrote on the earlier thread, from the little information the Links Trust has provided us with, I think they are just restoring the bunker to what is was like in the 1970's, and I think that this is a good idea.
More importantly, as you move this cause forward, I hope that you/we deal with the issue of "Preservation of what?" Do we want to preserve the course of today? Or the course of 2009 (before the most recent RHB change)? Or the course in the early 80's (when you first played it)? Or that of the 1900's, when Low added the bunkering to the outward 9? Or that of 1855, before Playfair and OTM and Robertson nearly doubled the overall acreage of the course (by reclaiming from the gorse the land now used for the outward 9) and doubled the size of the greens? Do we want to 12th green to be replanted in heather or the Shell bunker to again be filled with shells? Etc. etc. etc.
The "slippery slope" you and others talk about has been slippery for more than 150 years, and in general I think the course is a "better" one than the one I first played in 1978, even though perhaps less interesting due to modern maintenance practices and modern balls and equipment. The course could easily withstand these rolbacks, but unless the rest of the golfing world rolled these back too, what would be the point? Even if you did a simple thing like slow down the speed of the 11th green so that back left pin position could be used more often, what would you do with the rest of the greens? Cut each of them to different stimpmeter settings? That would be interesting, but how would would the average golfer (much less the average PGA Tour pro) like that? making Hell bunker the unraked, crumbling mess that it was in 1978 would be interesting, but how would we like that? If we want to treated the Old Course as a museum, fine, but how many will want to play it, and at what price?
