Debt free or away from densly populated areas when SHTF?

[T-oddity]

For me it is being debt free which I achieved this year, I chose to stay where I am instead of moving to some where less populated due to family and friends, though the population round here is nothing like London I had intended one day going somewhere more remote, but now retro fitting the house and being as self reliant as possible to cut our out goings to a minimum and with an eye to buying a small patch of land not too far away as a bolt hold if the shtf.
