So much depends on which Sit-X were to occur, I honestly don’t think there is a THIS IS BEST with all the factors to take into consideration.

My current location is on the edge of a city, I have water catchment inplace we use for the garden a couple of streams and even 3 lakes within 15-20minutes walk and then there is the local canal so thats water plus fishing.
We grow some of our own food, have room and plans to expand, we have birds, rabbits and squirrels to hunt woods, hedgerows and wasteland to forage……….. kinda the best of both worlds depending on what should happen.

If at first you don't succeed, excessive force is usually the answer.
