I agree with Blue Jay that stemming the tide of cell phone prevalence is not a possibility, BUT I would like to think that our national parks are a last bastion in which wilderness takes precedent over the encroachments of society. I would like to think that Blue Jay is wrong about hikers in support of cell access throughout the few remaining wilderness areas and would hope that more importantly they would be concerned with preserving the integrity of the wilderness they seek. However, I believe that the avarice of humanity knows no bounds. All be damned for our convenience.
