Played 9 holes at Cashen Course in June 2008. I have a vague feeling of dislike. As was customary during the week I played in Ireland, the wind was howling. Parts of the course could not accommodate the conditions. One of the greens we hit into, perhaps number 4 or so, was no more than 10-12 paces deep, with an uphill shot downwind. There was absolutely no place to miss the shot, as the dunes were essentially vertical in front of and behind the green. That design might work where there is no wind and the greens are soft, but it did not work there. And I really didn't care about score, it just wasn't any fun to play the hole. I do remember that I liked the opening hole, particularly the approach, and there was a good 170 yard or so par 3 that played slightly downhill to a tabletop green. As I'm writing this, I am recalling a number of shots where it was fairway or lost/unplayable ball, with no option in between. Maybe that's what fosters the vague dislike.
Full disclosure: The wind was blowing so hard that day that even the Old Course at Ballybunion was nearly unplayable for us, a group of decent golfers.
