Here's a thingie I came across at unfogged—indicate the states you've been to in bold, underline where you've lived, and italicize your current home.
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.
Now, I merely passed through a bunch of the bold states, and had short business trips to others. I don't even know about Kansas. Did I pass through it on a childhood vacation? That one business trip to Kansas City—what state was I in, exactly? Poor Kansas.
Connecticut was...lovely. (My first time going to CT was this past weekend for the crossword tournament.) I was in a shuttle van or the hotel the entire time, except for that dinnertime trip to the mall across the street from the hotel. I've paid CT sales tax, but I can't really say I've been there, you know?
