My goal is 40 countries but I'm not there yet. I've made in to 36 - though 3 of them I never got out of the airport. I have not been to Micronesia or Antarctica but I've got the rest of the continents covered. Places I've "lived" include Canada, Mexico, Columbia, Suriname, Costa Rica, Holland, Germany, Russia, Egypt, Korea - and here of course.
My favorite place just passing through was Cuba. It was a stopover on the way to Russia on an Aeroflop jet. We got out on the tarmac and walked to the terminal. I did the good pope thing and kissed the ground. Same ol' bitter dirt as anywhere else.
