Following the (admittedly small) herd, but then I've always wanted to see a utility like this, and here it is.
This covers all of the states that I've been to. Discounting Texas and Missouri, these are all states that I have been driven through/covered the ground myself.

Somewhere, buried in things, I've actually got a pile of those 'state patches' that I always meant to sew on to a jacket or something. I was collecting them as a kid, after one particularly long family road trip. I should dig 'em up and see if they're still holding together, it'd make for a fun jacket, still.
