Hey /out/, I'm working on a notebook where I can write all kinds of useful tips and methods for survival. I'm trying to develop an index to this notebook which are the different topics. So my question is, what topics should this notebook include? I'll name the obvious. Shelters/fire, boats/water, trapping/cooking, fishing, dangerous animals/plants,edible mushrooms/plants, first-aid. Anything you think I should add to the index?
