Depending on the date, I'd definitely consider attending! Last time I've been to Ireland was before I started geocaching, and checking the map nowadays I get a glimpse of what I missed out on, so I'd say the country itself, the chance to go caching and the chance of attending an event on the Emerald Isle would be three very good reasons to go back to Ireland! Especially since I haven't been to County Cork yet!
