Nope, but I've been there twice. Went all over Ireland in 2007 or 2008. Started in Adair and worked my way to the rest of the country, ending in Dublin. Beautiful country, and now I can't drink Guinness without thinking about how much better it was in Ireland.
I would definitely come back. If the economy were stronger there, I wouldn't mind living in Ireland. However, my whole family is in the states, and there are better opportunities to make money here.
