Bob, Niall - you're both right.
I simply meant to suggest that in Dr Mac's time golf was still primarily a "gentlemen's" game - the few exceptions like Marion Hollins and Joyce Wethered being precisely that, exceptions.
Yes, out went the cross bunkers and in came the strategy, but in large part all for the sake of the middle-or-upper-class Bernard Darwins of the world (give or take a few strokes or a few thousand pounds here and there).
TD's courses are serving a much broader range of golfers today than Dr Mac's would have served in his own time; and that Dr Mac's courses do serve a broad range of golfers *today* is, at least in part, because of the vast changes in technology.
But I'm nit-picking. I enjoy trying to understand and figure out for myself how and why something that works so well, works. In that context, neither the conventional/historical explanation nor even that of the architect himself strikes me as satisfying. No insult intended, of course, to either the historical record or to TD's communication skills.
