Hmmmmmmmmm
I like the way Rich looks at this... that is, it's not so much quirk, or if a course particularly makes one smile, but rather does it charm?
And to that end, I believe Torrey Pines is charming. Heck there are only so many courses in which one can retrace the footsteps of the greats, particulary recent footsteps... and although Torrey is a very difficult golf course, I have to believe if I played it again soon, I would be charmed. There are some very difficult shots to be played there (from what I can see - haven't played the current version) and I'd enjoy tackling them and stacking my meager self up to Tiger, et al. On top of that, the views are lovely. But mainly it would be in the play there... no way could I play it like they do - I have not even close to the skill required - but trying to find away to get around in a decent score would to me be very fun. In this way, it would be charming.
And the same goes for Bethpage Black.... and Oakmont... and Medinah... and Olympic Lake... and other courses normally thought of as long brutish slogs.
Of course this is also not the ONLY way a course can charm. I believe Kalen describes Pacific Grove Muni very well in this respect - I am charmed by that course also, for just those reasons. Every time I play there I wonder why it's been so long, why I don't play it more often. That course most definitely has charmed me... and it's 5500 yards at most and surely has never and will never host the pros.
But Pebble Beach to me is more "charming" than Pacific Grove muni. And overseas, Muirfield is thus more charming to me than North Berwick.
All are fun to play. All make me smile. But I like looking at "charm" this way.
ONE CAVEAT - to me also "more charming" may or may not equal "better."
