I couldn't resist adding in the countries and cities that I've at least visited (I count a "visit" as being on the ground or in a building in a place - even an airport).
The site lets you identify countries and states/provinces that you live in, have visited, or want to visit. Here are some screen shots from my input...
There is supposed to be a way to plant these maps on my blog, but I'll be darned if I can figure it out. Therefore, I went with screen shots.... Hmmm, maybe I should put them on my Facebook site!
If this appeals to you, go sign up for Where I've Been and make your own maps to impress your friends. And if you can figure out how to add them to your blog, please let me know!
