navigation is an easy one, a physical map is as portable and efficient enough. re. the rest i feel the most important thing is to develop a solid social infrastructure. e.g. know your neighbors and be on good terms with them. know the places where you can get a hold of your friends if you need to. know your community and actively participate in it. that sort of thing. this is your safety net in case something goes awry.
