The Night Climbers of Cambridge

'Night climbing' is a tradition in Cambridge dating back hundreds of years involving students scrambling over the historic architecture of the city. Whilst the university strongly discourage the activity, unofficial guidebooks do exist about the best routes. In a programme made for BBC Radio Cambridgeshire, Chris Berrow finds out what it is all about and talks to a selection of 'night climbers' including a sitting MP and a national newspaper journalist.
