If it is, it's a secret because the people in Northern Ireland are lying. I've thought about going to see it a couple of times, only to be discouraged from doing so by different people (members and caddies) at Royal County Down.
first off, I've done a ton of caddying in my day...
...but the last thing I'm going to do is rely on the opinion of a caddy on something like this. and I can also probably construct a case that RCD member's are less than arm's length when giving an opinion on Ardglass.
while we were there we played:
RCD (twice)
Royal Portrush (Dunluce twice, Valley once)
Castlerock
Rosapenna (both)
Portstewart
Ardglass
not a bad lineup...
...we all thought Ardglass was delightful and would definitely go back again in order to see the whole course.
