writes "The National Park Service is finding technology to be a double-edged sword. While new technologies can and do save lives, the NPS is also finding that unseasoned hikers and campers are now boldly going where they never would have gone before, counting on cellphones, GPS, and SPOT devices to bail them out if they get into trouble. Last fall, a group of hikers in the Grand Canyon called in rescue helicopters three times by pressing the emergency button on their satellite location device. When rangers arrived the second time, the hikers complained that their water supply tasted salty. 'Because of having that electronic device, people have an expectation that they can do something stupid and be rescued,' said a spokeswoman for Grand Teton National Park. 'Every once in a while we get a call from someone who has gone to the top of a peak, the weather has turned and they are confused about how to get down and they want someone to personally escort them. The answer is that you are up there for the night.'"
