Note that I only transited New Zealand and didn't go groundside on my way back from Aussiecon Three, so that probably doesn't count. Mexico was a couple hours one afternoon during the El Paso Westercon. And the map treats all of a country, including big ones like Canada and the USA, as a single entity. I've been to about 2/3 of the US states, four Canadian provinces (the four that have hosted Westercons and Worldcons), and one Australian state.
If it weren't for Worldcon, I expect the count would be even lower.
Thanks to king_espresso for reminding me that this map exists.
