I bought it at a Better Value hardware store. I keep it clipped to
the outside of my bag. Only once have I ever felt it might be needed
in my multitude of loner hikes and had plenty of time to assess the
situation and prepare. I refuse to let fear rule my world but am also
certainly not foolhardy. The peace that letterboxing hikes provide
for me is precious beyond measure.
