Hi - I'm making a film - can you help?

Adam, this is kindly meant, but you do not seem to understand what prepping is about or why no-one will talk to you. No-one will tell you details of their preparations - the idea is that they are under cover; secret. or whatever you want to call them. This is to protect oneself and more particularly one's family in times of trouble. Why would someone blow their cover - particularly to the BBC?
I suggest you advertise in one of the national papers. You might get some very entertaining responses.
