Here in the Pacific NW, cell phone coverage outside of urban areas is so sparse that I often lose signal from 1/2 to 1 hour before even reaching the trailhead in my car. (That's true in most sparsely populated areas of the Western states.) I don't take the phone with me, just turn it off and hide it in the deepest recesses of my car. (I do carry a PLB, so I have a button to push in case of life-or-death emergency.)

I'm also somewhat of a luddite--paper map and compass have worked fine for me since I learned to use them at age 6, so why bother with electronics? It's not that I can't learn something new, (I'm getting really immersed in Civil War history, my latest hobby), it's just that I can't see any reason for doing so--no motivation.
