What an enjoyable day. This was my first visit to Oxford and I certainly plan to make the journey again. Much of the enjoyment was hearing the anecdotes and history of the area from our guide Chris - thank you.
I would have liked to stay longer but by the end of the day my legs had had enough and my intuition to catch the Cambridge bus when I did was well founded. Like the journey inwards the bus was again full and passengers were being refused.
Here are some images presented in a slightly unusual rendering
