Spinning the Globe: where to visit in Ireland

In July, I will have the chance to be in Ireland for a few days. I've been pouring over travel books, blogs, and of course Irish America's April/May 2010 Top 100: People, Places and Pleasures issue for the best places to go. I know I will have one day when I can travel (by bus, train, car) out of Dublin to one of the counties. I have no idea which one to choose! So I'm writing this blog post in hopes that some of you that have visited Ireland more frequently than I (I've only been once) can post their favorite destinations in Ireland. Thanks everyone!
