Hello. I am in the process of writing something where the MC and another character moves from Oxford Street to Biggin Hill during the start of a military lockdown, because they hope that the military will forcus mainly on the central city. I have two questions: 1. How long would this approximately take? On foot and by car. Tube rides are not an option. 2. What does it look like around there? The images I could find show tiny villages and scattered farms. Is this correct?
