i saw some tv footage of the area where he was hiking, and i knew, as urbanized as i am, i would never go to a place that remote. do hikers/climbers carry satelite or cell phones when they go so far out? should they? do they have to check in with a ranger if they're climbing in a state/national forest so someone has an idea where they might be? i know one of the climbers that died on everest was able to use the satelite phone to speak to his wife in new zealand as he was freezing.
