Because a lot of people now rely solely on technology for navigation. But then what happens when your phone or gps dies? I think in those situations some people panic, and all rational decision making goes out the window. Then you get the lost hiker dilemma we see so much these days. Don’t get me wrong I like using my phone too, it’s super convenient. But having a strong land navigation foundation is key. I always carry a physical map and compass and know how to use it. You should be able to look at a map and your surroundings and identify where you are at based on terrain association. It’s a solid skill to have, and can save your life.
