I've been to Canada, New Zealand (sadly for 10 hours only), Australia, Spain, Portugal, Germany, Italy, the Vatican (if you count that as a country), Switzerland, Ireland. If you count countries where I did not leave an airport/train station, then also England, Austria and France.
I've been to a lot of different states, but the only other countries I've been to are Canada and Taiwan. But in a few months, I will be on my way to France for half a year, so I plan to get my passport filled up while I'm abroad.
Nothing I'd rather do then travel, well, lets see, I'm from Ireland, and.. In Chronological order..
United Kingdom, France, Portugal, Italy, Austria, Leichtenstein, Switzerland, Germany, Thailand, (Istanbul to Cairo unplanned trip) Czech Republic, Turkey, Syria, Jordan, Egypt, (working Holiday) United States [New York], Spain, Belgium, Wales, and currently living in London, far from home in Cork.
I had a nice daytrip from Buenos Aires over to Colonia (del Sacramento) in Uruguay back in May on my way home from my first season on the Ice. Colonia was a really welcome break from the noise and clamour of BA, and it's pretty awesome to take a ferry ride across a river that wide. Happy trails!
