It's time for a little update. June in Poland, Lithuania, and Latvia helped fill out a bit more of Europe. There are still many places above Türkiye that remain unexplored.
I keep an old resume that includes a perpetually-updated listing of countries or territories I've seen. I also keep a Flickr album that has a representative photograph from each of these countries or territories.
Yet, in addition to those ways, I once started this online Matador Network travel map. The web site provides a checklist organized by region. Once a country is checked, it appears as filled on a corresponding map. I always point out when we visited the city of St. Petersburg in Russia for just two days, a whole lot of the world lit up! Using this to show where one has been is a little disingenuous. The travel map, though, does help to show vast swaths of the world that we've missed.
I know that we plan on adding only 5 or 6 new countries during our upcoming winter. When spring comes, however, most of Africa will still remain grey.
