Agreed. At least as far as the unpredictable. It's another real world limitation. You can't anticipate what you're going to happen upon so you just have to adapt. Take it with you somehow, or stick around so you can take advantage of it. We can't plan for EVERY possibility.

I consider foraging for food and fire supplies part of everyday life at camp or on the trail, nevermind in an emergency or bug-our scenario, so I plan for that. I bring fire and food with me but if I can suppliment that, or avoid using those supplies, I will. In fact, I'm about to upgrade from plastic shopping bag to something more reusable and durable, because this is such an every time activity for me. To your point, I'm talking a few pounds, not much more. (Not trying to be fancier, or hoidie toydie, just better for Mother Earth.)
