As parking is somewhat awful in Cambridge, it has been suggested by Tim (thank you Tim) that we meet at the Babraham Park and Ride (off the A1307 Haverhill to Cambridge Road). I would suggest 3.30pm to meet. We can then have the pleasure of a short bus journey to the Cambridge Main Railway Station a short walk from the Botanical Gardens. Once finished there we can go back to the Railway Station to catch a bus to the Babraham Park and Ride. Decamp to the cars and go to the George at Babraham for a meal.
