Interesting question. Like the others, I bring the usual suspects but lately have also been packing more emergency stuff in case I get stuck in the woods. I have fire starting material, basic first aid kit, extra para-cord, extra batteries, two sources of light (flashlight & headlamp), extra knife, water purification tables, Swiss volcano stove, etc. The main thing I am missing now is some sort of shelter. I have a cheap tarp that would work but it is heavy and bulky. I am looking for a tent material type tart for lighter weight and smaller pack size.
