advice upcoming visit to Bletchley Park / comp museum

IMHO even worse. Its 177 miles of motorway which is the usual way to get around London. As usual it was built as cheaply as possible so originally was only three lanes in each direction. These days its mostly 4 lanes, but that meant removing the hard shoulder and replacing it with spaced refuges. I would say its never without an incident somewhere along its length. The stretch around Heathrow where the M40 and M4 join is especially bad. I can see on the "trafficengland" web page http://www.trafficengland.com/ that even though its 9.30PM there is currently one reported incident with a lane closed on the stretch approaching Heathrow from the south (so Gatwick) If you really want to do justice to Bletchley you need two days. The Bletchley Park Museum which has lots of information about code breaking and also the Amateur Radio station needs 3 or 4 hours to do it justice.. They have several encryption machines including Enigma. However what for me is the interesting hardware, so the Turing Welchman Bombe re-build and Tommy Flower's Colossus re-build are at TNMOC which is a separate museum on a separate part of the site. That?s where I usually go (But I am on the Members Club committee). That is imho also worth the best part of a day to visit. If you want to visit TNMOC you go past the entrance to the Bletchly Park Trust entrance and drive up the side to the TNMOC. The security man will usually guide you. Dave
