Royal Dublin.
It doesn't get much love here (certainly not from Doug Wright) but I played it as a total afterthought; I squeezed it in on an afternoon and took a city bus to play it. On the way out, through the city, toward the docks, I'm thinking "how the heck can there be a good course here?" Well, there is. It's not among Ireland's very finest, but it's a genuine, worthy links.
