the distances in the UK are much smaller than in the USA, the whole length from one end to the other is..i think..less than 1 thousand miles, on American sites they say you should be a full gas tank away from the city, that just isnt possible in the UK, most of us who have already got out of the cities are maybe an hour, an hour and a halfs, drive from a city, 30-40 miles, some people even less, although in my case my nearest "cities" are not exactly large ones! having said all that, there are places we can go in England where someone can remain hidden for a long time, its all about knowing ones own area well, and knowing where to go, its no good being an "armchair" prepper, some foot slogging and driving will be needed!
Some people that prefer to be alone arent anti-social they just have no time for drama, stupidity and false people.
