I finished it on Friday—only to wish that I had added two more sentences (isn't it always the way?). Jarrod Fowler had sent me some very very useful material on asynchronous phenology, and I had forgotten to add it. So I just did. That and Yves Klein's Hiroshima, about which I had no idea until I saw it at the Menil this Sunday. And the "elephant's foot": a terrifying lump of melted reactor core at Chernobyl that will kill you if you look at it directly. Like Medusa. So I just resent it...hope it's okay.
I've never been late with a book deadline so I'm hoping the kind people at the press will be all right with this addition.
