Cracking the Code

A visit to Bletchley Park yesterday to learn about the code breaking activities of World War Two.  9,000 people worked here at one time.  Interesting and something ticked off my to-do list.  However, it did eventually get a bit repetitive and we'd had enough by the time we headed for home.  There's only so much you can say about code-breaking, especially as some of it is still shrouded in secrecy.
