I consider myself to be pretty self sufficient and would likely be classed as an "experienced hiker". Nonetheless, I have spent a couple of nights in pretty inhospitable situations and have returned home from an afternoon hunt at 2 AM or later more than once. I have also ended up in places somewhat removed from my intended destination when I've gotten distracted by a set of tracks or succumbed to the urge to see what was around the corner. So I guess it can happen but there has to be more to this story and I wouldn't be surprised if there was a mental health issue involved.
By the way, one can call out this particular woman in this instance but Jorge, as usual, let's his butt do the talking when he hints that no woman should be out by herself. GD
