Three come to mind:
Troon: Putting aside the Postage Stamp to the Railway, I find it a vapid, tuneless chore . . . . 1-7 and 12-18 is like having 7 ugly girls in a row on your dance card, twice, with a brief respite in the middle. The whole experience left me with a bad taste in my mouth - and it does not help the snotty-ass members make it very clear they don't like Americans.
I showed up wearing a tie & jacket, because Dad told me the club was impossibly stodgy and severe, but even my most unctuous, deferential, putridly polite rap got me the same "who are these American cockroaches?" attitude from virtually every person I came in contact with. And did I mention the course sucks eggs? I give it a generous "4" . . . . . maybe. By contrast, my personal nivvana is right down the street at Prestwick.
Next time, I'll play the Portland Course with some lovely, mature Scottish lassies.
Atlantic GC: Nice club, kind members who make you feel welcome - but the golf course is an incomprehensible mess of criss-crossing bad ideas - with bunkers that are not only an ocular offense, but apparently arranged using a blind-folded drunk with a dartboard. Everybody else seems to dig it, but I don't get it.
Torrey South: Take away the ocean, 3-5 and 13-15 - and you are left with an awkward routing, with putting surfaces less interesting to read than the fine print on your PPO. It makes Sandpiper look like a design masterpiece and that is not a compliment.
