I'm not sure if anyone can answer this or not because I'm not really sure if I this forum is for my kind of question..but I'm gonna ask it anyway...

okay, in the survival guide thing, it said that when in the desert, for shelter you can take two trash bags, and make a sleeping bag type of thing, but my question is, what do you do if you don't have a trash bag, or any supplies at all for that matter.....again, not sure if I'm at the right place to ask this lol
