It's the greatest place on earth, if not exactly the greatest place on earth for golf.
I was very happy to have played Metairie on my first visit though. It's about the worst property for golf I've ever seen - completely flat, in a flood plain, and set on a parcel that's shaped like a capital letter L. And I think that makes it a really cool lesson in golf course architecture, because the Raynor templates (as executed by Joe Bartholomew) show in a pretty unadulterated and unadorned form.
When you play a course like Old MacDonald, you get to see template holes at their sexiest, in an awesome setting that lends a whole new character to their fundamental appeal. And that's super cool. But as a student of architecture, seeing the templates in a completely unremarkable setting helps shine a brighter light on that fundamental appeal. It's worth checking out, assuming you can arrange access.
