I am pretty good at identifying US accents. It bugs my wife when we are travelling and I talk to the locals. I always ask certain questions just to hear them say certain words (I know I'm a little weird). You are right it would be awesome to visit Ireland and the UK, I'd be in heaven with all of the different accents and phrases. BTW we can't leave out the Canadians (My knowledge of "Canadian" is limited to "The Kids in the Hall"-- one of my all-time favorite shows)!
