Not many states filled in, but I did do a little bit of international travel earlier this year.
Green indicates states I've visited, or at least driven through/stopped in for some notable period of time.
Grey indicates states I have never been to.
Blue indicates the state of my current residence.
Red indicates a state I've only been in via an air layover (right now, that's just California, as I was briefly in LAX, although I was rather young and do not remember it. But I may get to change it to green as I might visit family out in San Diego soon).
