I am prepared to drastically reduce my need for fuel in various ways. For one, I can cover tens of miles every day by bicycle. Of course, that is with just one bag of stuff.
The key to survival would be to virtually, if not literally, ween yourself from the need for fuel.
You don’t need gas to ride a bike, but in a bad situation how safe is it on a bike? A downed tree, you stop and they grab it and you. I’m not criticizing you I’m just thinking of how easy it would be if some determined people wanted what you had, how they would get it.
