- Turkey in Europe (Istanbul)
Also, Jeju Island (South Korea) was added to the list this year, so I have a total of 31.
My pace of two a year was helped by the fact that I attend two particular conferences every year, one of which rotates around Europe and the other around Asia. Each, however, rotates entirely among countries I've already visited for the next two years. This year, though I missed the European one, it repeated also, so I visited no new countries this year for the first time since 1999. I might go to one in Hungary next year, so there's always the chance to add to the total through other conferences.
