Not me. I would be content to have a single shot 22 and enough ammo to get me by. A good knife would be better for me. I can find much better ways to deal with bears and other would be predators after ditching out. In fact, I'd prefer becoming the predator of them than letting them consider me their chow.
Yet another reason why I don't need to go out into the wilderness just to explore what's there. Every trip needs a purpose, for me anyways. Otherwise it is just reconnoiter??? Purpose being a material objective. Surviving a wreck is just an opportunity for material gain, in that case.
It is a different perspective than most people might have, but then if you've read my posts, you know that's me.
