I understood that.
What I wanted to ask about was that it seemed a bit odd to just have caches lying around 'for their own convenience' without an ulterior motive of some sort such as this very situation.
Of course, they really could just be leaving them around here and there because reasons, and considering the nature of the area, it might make sense, though it seems too logical a leap to make, I think.
Wanting to take walks alone make sense, leaving supplies of such nature, not so much.
