but wouldn't dropping the cell phone be a small safety issue? I don't always have coverage, but isn't it nice to have one in case of an emergency especially since I usually go solo"
I almost always go solo, and have been doing it since before cell phones. As have 1,000s of people for years. More than likely, an emergency far from other people is going to happen in an area of no cell phone coverage anyway — at least hopefully you can hike beyond the range of cell towers :)
But if you feel more comfortable with one, that is up to you. And I am sure we can find stories of hikers who's lives were saved because they had a cell phone. I always try to analyze how they got into an emergency situation, and whether or not it could have been avoided. Of course a burst appendix 200 miles from a cell tower is something one probably cannot avoid by planning, or a rare attack by an animal. But then, life is a risk anyway; no guarantees, other than you will die sooner or later. Most of us prefer much later.
