I live in Cambridge. Its full of bloody foreign students at the moment, you can spot them a mile off because they all wear orange backpacks.
Cambridge is really nice. Come visit Kings College Chapel, and the Fitzwilliam Museum (recently refurbished, looks good too!), or just sit in one of the many parks (if the weathers ok). Not bad for shops either, but not many Cambridge-specific shops. Sometime around now is the Folk Festival if that floats your boat.
