I think you have it right regarding the past 2-3 years, which have been (hopefully) an anomaly, weather-wise. No course in the UK or Ireland which I played over this period was as good as it was in the 5-10 years previous, but I do not blame committees or greenkeeprers, just Morther Nature.
Which means, of course that I strongly disagree with you, Sean regarding the past 10-15 years, which I think, overall, have shown tremendous progress in greenkeeping knowledge and practice. I'm not sure how long you have played over here, but I'm in my 31st year of playing the great and not so great in GB I, and I can guarantee you that Adrian is right about the relatively poor standard of green conditioning in the late 70's an just about all of the 80's.
To get back on topic, the first time I heard of the legendary Nairn greens was in the mid-80's, from some friends who had been competing in the Scottish Amateur when it was played there at that time. I had played Nairn some years earlier and hadn't thought much of it, so was surprised. In retrospect, I also remember that Dornoch, for example, was as poor as I have ever seen in at that time, which unfortunatley coincided with their holding the British Amateur in 1985. Maybe Nairn just happened to get it right at a particularly appropriate time and when most other courses were relatively poor, and has been at least partically living on its reputation ever since.
I might be playing Nairn in May, and if I do will report back as to what I find.
