don't fret over this guy. If I was poor I'd love to be given mylar. But than that's probably why I am not poor. I keep a couple 4$ mylar blankets and poncho's stashed in all my vehicles and buildings in case of a power outage or a blizzard or whatever. May I suggest a small book that helps the reader to identify edible and poisonous plants in your local area. Can hobo's read? maybe it could just use pictures and symbols. I once found a multitool at a pawnshop for 5$. it wasn't a Leatherman but its sturdy enough, just had to give the knife in it a sharpening. I wonder about making medical charcoal. the store bought kiln activated fine ground palmtree stuff is pretty expensive but they say you can make your own pretty cheap with just firewood.
