As someone who observed and modestly participated in the Old Macdonald design process over the last four years, what most surprised and pleased me was the way in which the original template idea migrated. There are some holes that adhere more closely (Redan -- 12) and other that vary wildly (Maiden -- 14), and some that don't even pretend to be emulations of anything but are pure originality (Ocean -- 7; Westward Ho -- 15).
All of that evolved because of a commitment by Doak & Urbina to making a golf course that fit the land rather than forcing holes onto the land. The real guiding principle with CBM -- as I explain this week in a forthcoming column in Golfweek -- is that the course should be big, bold, interesting, fun and on the outrageous scale.
There was also the anticipation of Jonathan Cumming's concern that the course needed to be economically viable. If you build a course for GCA maniacs it will go broke for two simple reasons. First of all, there aren't enough out there to make a place work -- for all of the discussion and enthusiasm and interest in architecture, it's still ony a small, esoteric niche of the wider golf market. And second, they all seem to be raters who don't pay!
So Old Macdonald had to have wider appeal even as it was true to its mission of honoring and embodying Macdonald design principles. Copying or using templates was actually also infeasible because it was never clear what the template would be -- the original in GB, NGLA, or some other Macdonald/Raynor version. I clearly remember the surprise of the folks at Littlestone in Kent, England, when they were told that their old famous 16th hole was the inspiration for Lido's 4th and Old Macdonald's 17th. That hole at Littlestone still exists in basic form but changed so much in subtle ways years ago, and I had to scrounge around out there in the dunes to find what had presumably been their alternative fairway.
But while there is a only a small corps of dedicated architecture junkies, there are enough traditionalists who like links-style golf, who like walking, who like playing 36-holes a day, and that's the market at Bandon. It's a form of "narrow-casting" that's been successful in cable TV and that doesn't need to appeal to the widest possible public. So all Old Macdonald has to do is be in that "narrow-cast" market and be maintainable for a reasonable cost -- which it is, even with greens that average 14,600 square feet in size. So I suspect that Bandon and Old Macdonald will remain economically viable, even as they are susceptible to market forces, because that little corner of the golf market will remain pretty loyal. And for all the trouble of getting there, it's still easier and cheaper for folks in the Western 2/3rds of the US to get there than to get to Scotland.
