Well, let’s see - my goal is all 50 states before I die - got some catching up to do, apparently…
USA
[list=1]
[li]Hawaii[/li][li]California[/li][li]Oregon[/li][li]Washington[/li][li]Idaho[/li][li]Utah[/li][li]Nevada[/li][li]Arizona[/li][li]New Mexico[/li][li]Texas[/li][li]Colorado[/li][li]Illinois[/li][/list=1]
And British Columbia for Canada and Baja California, Mexico.
I’m in my thirties and my travel experiences are still very limited. My home state is Idaho. The only states I have visited by car are Oregon, Montana, California (just the northern tip of it), Nevada (again, just over the northern border to gamble there), and Montana.
By plane I have been to Washington and Kansas. I have also been in Colorado, Texas and Utah but I only because I’ve had flight layovers in these states.
Lastly, I have been outside the U.S. In 1987 I went to Mexico with some students in my Spanish class. I have also been about 100 feet or so into Canada (British Columbia) when I was with my grandparents. We drove through the panhandle of northern Idaho and turned around at the border.
Sticking to the OP, I’ve been to all 32 counties of Ireland.
I’ve also been to 10 US states, 3 Australian states, 1 Canadian province, 10 of the 15 EU member states (damn those scandinavians for joining!) and a fair few other places.
