I am surprised no one ever came out with something like this before. At World66 you can create a map of all the states or countries you’ve visited. Here is the map I made of states I’ve been too. I won’t count a state unless I’ve spent at least few hours there. Driving through with no stops or flying over doesn’t count. If I’ve slept over there though, I do count it. Yeah, I have a lot of ground to cover if I want to get to all 50.
