Some of them (pp. 24-26) were written with a new NaNoWriMa, an Olivetti Studio 44 that I bought in West Virginia. It's a strange, long, luggable typewriter with a weird shape and color, and a peculiar charm. (Image from the San Francisco Museum of Modern Art.)
I'm happy to have shot beyond the length I reached for NaNoWriMo 2008. This is now the longest piece of fiction I've ever written.
