Visited Countries of the World
The wiki website World66 allows users to create a map of the countries they have visited. My map is above, showing the 185 countries I've visited according to their list. However, by my count I've been to 196 countries and territories, including these places missing from the World66 list: St Pierre et Miquelon, Zanzibar, Canary Islands, Isle of Man, Northern Ireland, North Cyprus, Hong Kong, Macau, Easter Island, Tokelau, and Wallis et Futuna. Northeast Africa is one of the biggest holes in my map and I've booked a trip to Ethiopia for mid-January.
UPDATE: In December, 2008, I visited Turks and Caicos Islands, and in January and February, 2009, I toured Djibouti, Ethiopia, and Somalia (Somiland), raising my total to 189 countries on the World66 map or 200 countries in total.
