I'm currently in California, our last trip was to Latvia, Lithuania, the UK & Ireland. The only question is where to next? I've visited 83 countries and I hope to see them all again plus some more. For a list of some of the UNESCO World Heritage sites I've visited click here.
Abu Dhabi, Angola, Argentina, Armenia,  Australia, Austria,  Belgium, Bolivia, Bosnia, Botswana,  Brazil, Cambodia, Canada, China, Colombia, Costa Rica, Croatia, Cuba, Cyprus, Czech Republic, Doha, Easter Island,  Egypt, Ethiopia, Estonia, FinlandFranceGermany, Ghana, Guatemala,  Greece,  Honduras, India,  Indonesia,  Iran,  Ireland,  ItalyJordan, Latvia, Lebanon, Lithuania, Malawi, Malaysia,  Maldives, Mali, Malta,  Mexico,  Morocco, Mozambique, Myanmar, Namibia, Netherlands, New Zealand,  Nicaragua,  Nigeria, Peru, Portugal, Poland, Russia,  Saint Lucia,  Senegal, Seychelles, Singapore,  Slovenia, South Africa,  Spain,  Sri LankaSudan, Sweden, Switzerland, Syria, Tahiti, Tanzania, Thailand,  Turkey, Turkmenistan, United Kingdom, United States of America, Uzbekistan, Vatican City, Vietnam, Zambia and Zimbabwe.

If I followed the Century Club rules, which  astonishingly includes territories and plane stops, I could add the following; the Canary Islands, Congo, Hong Kong, Bali, Hawaii, Wales, Scotland, Northern Ireland, Qatar, Tasmania, Chile, Azerbaijan, Puerto Rico, Japan, Hong Kong and Burkina Faso. Following these rules my "country count" would be 99, but here's a post written a few years ago explaining why I don't. However, perhaps when their way of counting gives me 100  I'll succumb to their lure, I'm  not above changing my tune!
