Your Recommendations, Please! 13 for 2013

Our dog Petal loves to lounge!
Hello! I could use your help- I'm planning a list of 13 Irish must-dos for 2013, & I'd love your recommendations. What great things do *you* think I should see/hear/eat/do? I'll also write & tweet about them, to let others know the scoop!
I've a few ideas myself, but need more- so leave a comment, tweet me @vibrantireland, or email hello@vibrantireland.com. The idea is to do enjoyable things that others might like to do, too- so nothing too smart arse, please :-) (Yes, I'm looking at you, A Year Of Festivals!)
Thanks a mil! Susan
