Everyone from Jordana Adams to Matt Yglesias has done this exercise.

I confined where I've been to places where I have spent a night, or, like Florida, visited for more than a drive-through, not states I've driven through or changed trains in, or whatever.

bold the states you've been to, underline the states you've lived in and italicize the state you're in now...

Alabama / Alaska / Arizona / Arkansas / California / Colorado / Connecticut / Delaware / Florida / Georgia / Hawaii / Idaho / Illinois / Indiana / Iowa / Kansas / Kentucky / Louisiana / Maine / Maryland / Massachusetts / Michigan / Minnesota / Mississippi / Missouri / Montana / Nebraska / Nevada / New Hampshire / New Jersey / New Mexico / New York / North Carolina / North Dakota / Ohio / Oklahoma / Oregon / Pennsylvania / Rhode Island / South Carolina / South Dakota / Tennessee / Texas / Utah / Vermont / Virginia / Washington / West Virginia / Wisconsin / Wyoming / Washington D.C /

UPDATE: Missed one. I lived in Natchez, MS, from June 1993-Jan 1994.
