Quite interesting to compare this with the "Fine Detail in the Gospels" debate. When asked about why they were in Salisbury, they mentioned the clock at Salisbury Cathedral being the oldest working clock in the world. If they were really in Salisbury to see the Cathedral, we would expect them to mention a detail like that. When I was 11 I went with school on a day trip to Salisbury, and came back with a brass running!
