As an American who came here to live permanently some six years ago I would recommend it to any of my countrymen and women. We are moderately rewarded as salaries go but find we can enjoy a full and varied life including travel abroad as well as fully entering the cultural life of the country. For all the talk and comparisons that such a thread will attract we still put one thing above all else, that is the kindness and friends we have found that has made the transition so easy. Also the tolerance, the non over-reaction and the puzzling humour of all those from the British Isles is something not to be missed.
Another more down to earth point (if you will accept the pun) one can visit any part of these islands (for that is what they are) so easily and experience a truly fascinating, fertile landscape of every hue and beauty.
