I was brought up as a poor country boy. Our family did all the old-fashioned methods of living. We heated with wood, canned food, did the garden and had a well, killed pigs/hogs, and had a cow for milk and butter. Oh yeah, we also had a two-seater for comfort and had that luxury until I graduated from high school. I still appreciate the information you try to get out to upper level folks. It takes me back in time.
What’s the bare minimum you need to navigate across land? For most people, that would be a compass and map. A basic road map is sufficient to get a rough approximation of the lay of the land. More detailed relief maps can help plan for elevation and estimate possible water sources but they also take up more room in your pack. Waterproofed or laminated maps are also extremely helpful. Lensatic compasses are the most reliable for little money. If possible, a compass and protractor are also extremely helpful for route planning. Obviously, not as essential but nonetheless useful.
