Not completely Linux related...but I am posting to the main list because it is a suggested meet.
I have just spent a lovely Sunday at Bletchley Park....It truly was a wonderful day out with plenty of exhibits (not all computer related) and a fantastic guided tour (that sadly was cut slightly short because of a seasonal downpour)
Highlights for me were seeing an almost completely operational Colossus...complete with a chat with the chap who is rebuilding it. and a small but wonderful vintage computing exhibit (the highlight of this being that you are free to play with the running machines) those two things were worth the £10 entry price alone...but there is plenty more to see and the tour gives a very complete picture of how Bletchley discovered how to crack the German codes.
I thought it would be an excellent day out for ALUG'ers (I am thinking more towards the end of Spring or Summer as I'd like a gap between this visit and the next and we get the chance of more predictable weather....I am happy to help organise this later in the year if it is of interest.
