We used to train there before being deployed on tour to Northern Ireland. One of the streets was called Letsby Avenue but as for the Falklands I'd be very doubtful.
Looked on Talbot's google map and there doesn't even appear to be a police station - probably due to the fact that there's no crime!
But I see they have Mormons and Jehovah's witnesses, which shows there really is no escaping them.
