Hi Ard Macha...Well I live not far from Cardiff. A couple of years ago, I went travelling around Baltimore, Washington, New York and Annapolis. Of course my accent stuck out like a sore thumb, (not really having a strong Welsh accent as I live on the border) people always asked where I was from. Usually when I was ordering dinner, shopping or whatever.
When I said Wales quite often they asked where it was, and then said - Oh is that near (or in) London. They really didn't have a clue where Wales is in relation to any other part of the country. And thought it was all England. Though a big majority also knew where it was.
So that was my experience, though I'm not saying none of them had a clue, but it did get a little wearing. And was always impressed when people knew where it was.
Ella
