Here are the places I have been to in the U.S. I know that I have probably driven through parts of Georgia, Maine, and Connecticut but I didn't include them because I couldn't think of anything in particular about those states other than similar stretches of highway. I mean does it count to have been there if you didn't even stop?
You can create your own visited states map or if you are cooler than me you can do one for the whole world
I would do the world map too but that is just too pathetic. U.S., Canada, Germany, that is all.
