Butcher, Thanks for the link to that 3-days-lost hunter story.
Given that she had firemaking gear and good enough firemaking skills to make a fire later when her facilities were even more deteriorated, I wonder why she wasn't drinking water from the creeks she was crossing & recrossing. Maybe she didn't have a pot to boil water in. The story didn't say, so that's my best guess. For whatever reason, her failure to hydrate was a big part of her ordeal.
While I agree with their list of stuff to take with you when you are out & about (which I've pasted below for those who didn't follow the link

), I find it interesting that they skip what is IMHO the most important item of all, as do most such lists. And that is the knowledge/training/practice needed to use efficiently the gear you've brought along in your kit. As others have noted, having the gear alone without knowing how to use it is status quo for most of the people around us. That lack of knowledge reduces the gear to simply being an anchor that slows the lost person down, which may help the SAR folks searching for them since they won't cover so much ground.
