Incidentally, Formal Hall is a Cambridge tradition. It is held on Tuesdays and Thursdays in termtime and involves wearing a formal gown, eating a three course meal and drinking wine and port in convivial company. Wolfson charges Junior Members 10.75 for this, and you are entitled to two free Formal Halls each year. Transport Try to do without a car unless you live a long way out of Cambridge, can't get about easily, have several children, or have a baby under a year old. Cycling in Cambridge is easy and enjoyable, as well as popular, thanks to the lack of hills and ample cycle lanes.
Buses are less well-adapted however.
The Stephen Hawking approach is probably the bravest, where you motor down the middle of the street ignoring the traffic, although that's not for everyone. The fact that the city centre is pedestrianised makes life a bit easier for buggies and wheelchairs alike. Shopping Charity shops sometimes have good second-hand clothes, but in Cambridge they tend not to be very good, probably because academics and computer boffins aren't known for their dress sense. London has better pickings. Try these links for a spot of virtual high street window-shopping.
