Where in the UK is Sandford?
In the greatest opening scene of any movie ever (IMO), we see the survivors taking refuge in that large farm house. The boy who they let in says he has come from 'Sandford' and the older gentlemen tells them that it is a few miles away. Where would this be in the UK? I'm guessing in the south near London (outside M25) area since Don finds himself eventually in Central London.
