A couple of years ago, playing alone on a cold wet fall evening at one of our local municipal courses, I was caught by another single. We joined up. Turned out he was from Ireland, working on contract for the local electricity company. In talking our way in we discussed his home club - Ardglass.
Fast forward a couple of years, and we're on a cruise around GB and Ireland. The golf coordinator breaks a leg and misses the ship. The concierge knows nothing about golf but is designated to help us make do. In Belfast we were supposed to go to Royal County Down. She calls ahead. It's for a Wednesday. Ladies day. No go.
I remember Ardglass, look it up on the Internet, and ask the concierge to book us there. We grab a taxi from Belfast (for a lot of pounds). The taxi gets lost and takes the long way around, but is good enough to not over-charge us, and agrees to come back and pick us up.
Ardglass turns out to be a gorgeous course on cliffs overlooking the sea, with two stunning opening holes. The people were very friendly. It wasn't RCD, but it was a real gem of a find on the spur of the moment, and after a lot of frustration. Well worth a return visit if we're ever in Northern Ireland again.
