I know that many of you are planning additional travel either before or after your research in Dublin. At some point in the past, I downloaded this document titled "My List of Do Not Miss Places in Ireland." I would like to give credit to the person who created this list, but alas, it doesn't contain a URL and I can't seem to find it on the Internet. To whomever created it, thank you.
Here's another site from About.com on the "Top Ten Sights of Ireland."
I've visited many of these locations with some still on my list for future trips.
