A friend came down from Maine this weekend to see the Pompeii Exhibit at the Museum of Science - if you get a chance, go. It's very---affecting. I don't know that much about Pompeii, or volcanoes (pyroclastic flow isn't really a part of my active vocabulary), but it was incredibly sad and yet fascinating all at once. I'd like to know more about it, but there are about a zillion books on it and I have no idea which one would fit best with my curiosity (this one looks promising, but the MIT library doesn't have it, bummer).
Lots of tromping in the snow. My boots have had enough.
