Sorry about the almost-week-long hiatus. For three days I was in Michigan visiting my mother and had neither spare time nor good net access. For two more days I was driving between Massachusetts and Michigan, and had even less of either. The only think that kept me sane was listening to Dune: House Harkonnen on tape. Books on tape are a great way to deal with long trips. I had never tried them before, and now I cannot recommend them highly enough.
