Alumni and guests are invited to join the Oxford and Cambridge Society of Hamburg for buccholic strolling, steaming kale and back-straightening schnaps. That means that we will be adding Boßeln - a kind of slow-motion bowling relay across the fields - to the bracing walk and pulling a Bollerwagen behind us to work up an appetite for the cabbage hot-pot to follow. If you were with us for the event last year, be prepared to up your game; if you're new to the idea of a Grünkohlfahrt, then read up and get prepared.
