Meet me at the base of Carfax Tower, on the corner of Cornmarket Street and Queen Street. Look for Kester holding a stack of large printed photographs, I'm the guide in the listing photos.
The tour ends near the Oxford Botanic Garden entrance on Rose Lane, just off the High Street by Magdalen Bridge. You'll be beside Magdalen College and the Magdalen Bridge Boathouse for punting, and about a 10-minute walk back to the city centre.
