THANKS to all those who e-mailed or blogged their good wishes. The weather could have been better, but it was nice to get out of town and drive down the coast. The best birthday presents were some Doctor Who tapes from the Jon Pertwee era and my son's drawing of Rocket Ship Galileo. The latter is the title of a 1947 book by Robert Heinlein, which we're currently reading at bedtime. Teenage boys and their scientist uncle soup up a rocket with a nuclear drive and take the world's first trip to the moon, where they fight Nazis! What could be better?
