We all know that when we go deep into the woods with the possibility of having to stay overnight either because we got lost or maybe injured. There are a few things we should have on hand. The obvious is water, light, and fire. But some of us have learned some usefull tips over the years.
I like to carry a zip lock bag with matches and a lighter and a metal match, spare pocket knife, compass, space blanket and a couple small heater packs.
I also carry a 35 mm film canister with some petroleum jelly soaked cotton. This burns long and is lights easily for starting your fire.
My pack contains a couple gauze pads and a roll of adhesive tape, some high energy snacks (granola bars) and a bottle of water.
