Jon W: The GB & I team LOST the Curtis Cup at Pacific Dunes, so the compliment was more believable. Of course, those ladies do have perfect manners.
Andrew: I hate to fall back on "knowing it when I see it," but I have listened to people try to define a "links course" for thirty years, and I still haven't heard a definition that doesn't require a lot of exceptions to conform to what I feel is right. Spending a year in the UK gave me a pretty old-school understanding of what links golf is, but there is always going to be a bit of a gray area, and some people seem to credit all gray courses in the UK as links, but not gray courses outside the UK.
When I referred to "being hoodwinked by marketers" I was referring to the many, many American courses (and now some overseas as well) which have been marketed as links even though they hardly qualify as such in ANY capacity -- playability, turf, conditioning, or being near the sea. Years ago a golf writer asked me if my Black Forest course in Michigan [18 holes through the trees] was a links-style course ... that's all you need to know about how abused the term has become. I personally think Pacific Dunes plays and feels like a real links, and even so I am reluctant to tout it as such, because the term is so poorly used in America that people might relate it to some faux links they've seen.
I do not think you can rule out a course from being a links entirely because of grass types ... Some of the links in GB & I have a lot of poa annua in them now, and there are outliers like Humewood. But it's awfully hard to get the links feel and playability with bermuda fairways ... Kiawah may be close to sea level, but it's mostly manufactured and the playing surface does not remind me of links golf much.
