Andy Ihnatko had just been talking about it, and then I ran across Joy's states-she's-visited map and there was the link and I started clicking states I've visited and...

I was surprised. Somehow it didn't feel like I'd covered so much of the country. 40 states. So only 10 to go. And they're in two easy clumps (except for Alaska, and I even have family there, though vague plan after vague plan to visit them have fallen by the wayside over the years). Seems doable.

Oh, and here's that link if you want to make your own map.
