Had an extremely light breakfast (2 slices of toast with marmalade) and headed off to Bletchley, arriving there about an hour later after an easy drive through moderate traffic. I parked the Zafira and we headed off to Bletchley Park. The museum is full of war-time artifacts, and concentrates on signaling, codes and code breaking. They have on display Lorenz encoders, 3 rotor Enigmas, 4 rotor Enigmas, and many things besides.
On display is a working version of the Bombe, the first decoder. They have also built a working copy of Colossus.
Everyone knows of Charles Babbage, Ada Lovelace, Alan Turin, and Admiral Grace Hopper. Hardly anyone knows who Tommy Flowers is. This is sad, because he built the hardware Turin needed. Mr Flowers needs Geek Fame.
Lunch was a steak & ale pie, and then we headed off. I took a worng-ish turn and we drove through the centre of Milton Keynes. That is an ugly town centre. Concrete and glass cubes, and car parks. It's worse than Civic in Canberra.
And so, eventually, we ended up at the Blisworth Tunnel, a 3km long tunnel that takes the Grand Union Canal from Blisworth to Stoke Bruerne, and the Waterways Museum at the top of a flight of locks. It's all rather good.
And then back to Offord Darcy for tea.
