Pat,
You have been very fortunate to have played the courses you alluded to in your post. Nevertheless, many more gems await you. Consider the North West, Rosses Point, Carne, Enniscrone, Rossapenna, Ballyliffin, and many more in that area. But that's just the beginning. What about the South and the South West? Too many courses, too little time!!!!!
Aidan.
