I've not visited any.
I'm not overly fussed about visiting America. Although it would be nice to go one day.
Don't know where I'd go though.
Anyway, since I can't post what states I've visited, I shall instead post the countries I have visited and the locations within;
England (No further north than Tewkesbury, Gloucestershire)
Wales (Southern and Western)
France (Paris plus Calais and various towns in Northern France)
Belgium (Bruges)
Italy (Rome)
Greece (Been to Aegean Sea (although Dodecanese island pf Rhodes), Ionian (Zakynthos), Macedonia (Halkidiki) and Central Greece (Attica - Athens))
