Sean,
I think some recent redos ( Enniscrone) and new courses ( Carne---haven't been to Old Head or Doonbeg) are designed with the US golfer in mind. This isn't a problem. I just prefer the rough and tumble of N/P and Portsalon to this look. Although both of these courses have made some changes that could be perceived as pandering to the same audience.
Mike,
I agree with you on enjoying the old look, although I wouldn't call the old look" rough and tumble". I'd call it simpler.(sheep and cow fences, less dramatic dunes, minimal maintenance)
I'd describe the Ruddy course at Rossapena and the new Machrahanish dunes as "rough and tumble"---fun occasionally, but not for steady diet.
N/P was one of my favorite courses when I visited in '97. I hope after the recent renovations that's still the case when I revisit this summer.
Even then the course had a pretty dedicated following of tourists and plenty of caravans
(mainly German)
I've included a few way off the beaten path this trip to ensure i still see some simpler courses in incredible settings (Northwest, Dunfanaghy which I've not seen, and Connemara Isles and Mulranny-two 9 holers which I have seen)
Portsalon is also one of my favorites ,but I've only seen the recent version '(07)
What makes you say Carne is designed with the US golfer in mind? Eddie Hackett did what he's always done-made use of a site with minimal cost and earth moving. This just happened to be a dramatic site.
I think the Irish,( like any other people) are always trying to improve their courses.
It happens that the tourism dollars finance that and yes many are American, but I'd say they are improving their courses to attract local and visiting Irish as well.
