Glen, It sounds like you have found the simplest solution. And for two reasons I find that exemplarity. We who walk in the woods often are in search of being self-reliant and independent. I don't know if those are the right adjectives or not, but you get the idea. I also subscribe to Occam's razor, "the simplest solution is often the best one." I go to the woods to get away from the complex life and listen to the wind in the trees, the sound of the river, and the birds. A phone, except for an emergency, is just a distraction.
