Niall:
I don't think North Berwick would be nearly as beloved without the Pit and the Gate, nor perceived as a great course as some do now. Yes, there are other fine holes, but without the quirky talking points they would not be enough, and the course's other weaknesses [it does have some] would be counted up against it. But you don't count up the weaknesses of someone or something you love.
This week I have played St. Enodoc, Westward Ho!, Saunton, and Burnham with a small traveling party, and Minchinhampton Old afterward. They are all so different that everyone in the group [well traveled men, women, and caddies from Sunningdale and from the Euro Tour] had a different favorite, and you could see why each favored a different course: it all came down to whether one liked quirk and unique holes, atmosphere, fairness, or challenge [in roughly that order]. I wish I had convinced them to stay and do Minch Old, but they were off to Sunningdale and it wasn't a great day for it, anyway.
