Maybe I am in a minority, but I was thinking about fiddlehead's post and it made me consider a few things relative to cellphones and my everyday life.
I first considered the impact of someone talking on a cellphone while being serviced at the checkout at a grocery store. That, to me is the epitome of rudeness. That led me to the problem of folks on the cellphone while driving. While some can pull this off, most seem to be distracted to the point where the surrounding cars are being unnecessarily subjected to someones negligence. These are just a couple of examples of people being selfish and inconsiderate of others.
That leads to a quandary in regards to the device itself. Hell, it ain't even a quandary. Pure and simple, the device is not the problem at all. The use of it is. I'm not a fan of movies and I have not spent much time in church lately, but cellphone use is most likely frowned upon in either location. If it was necessary to utilize the phone in either place, I imagine folks would excuse themselves to take care of that. Why would anywhere in the woods be any different, if not far more easy to pull off. The electronic devices are not going to magically disappear but with a little consideration and respect, the use of such devices would have little to no impact on any fellow traveler. That is and will be the reality from this point forward.
I carry a cellphone in my backpack. It stays powered off. I don't get it out in "public". No other hiker I encounter knows I have it. I like it that way and I can't see how that would be troublesome to anyone. I would say that the same could be said for an MP3 player or radio providing that the sound coming from either is strictly controlled. These things seem easy and obvious to me.
I'm sure that some feel that those devices have no business being in my pack. I'm also sure that some feel that they can utilize their devices any way they want and could care less who hears them, after all, those folks can walk away, or camp else where.
I think that with little consideration and respect, this issue could become the molehill that seems to be, and is, growing into a mountain.
