We’re in London, and trying to do a few human things before the lecture series starts. Since it was D-Day, we visited Bletchley Park.

Wow! My aunt used to love to give me enigmas when I was a kid, but she didn't have a neat-lookin' rig like that! Leave it to those Krauts! Where d'ya hook up the hose?
