Patrick,
It may be an American message board but thanks to the interweb we can all join in...
I have only made one trip to Ireland so far (though I'm hopefully playing RCD in September!) and as I was with my wife couldn't go all out to play golf, but as she likes ancient history I managed to play Portrush as its near the Giants Causeway. We then headed for the Newgrange sites and so I wondered where I could play near there, heard about Baltray and gave it a go. And I'm glad I did!
3, 5 and 14 were my favourite holes, with some of the holes on flatter land being not so great, but overall a good challenge. The rough was very long when I played so you also had to be straight off the tee!
The locals were also very friendly and welcoming... I was waved through by a couple of ladies. As I thanked them as I walked past, they asked where I was from and I just said I was from England, to which one replied that her brother was a club pro at Erewash Valley GC over in England - a course just down the road from where I live, and my brother used to be the assistant pro there, so her brother was my brothers ex boss! Small World!!!
Thanks to Bill for the link to the previous discussion thread and its photos. Also, just checked Google Maps and the satellite images of the course are now pretty good.
