I live out in the boonies too. I'm pretty much a survival kit myself!

I do carry a leatherman with me all of the time so I have something that I could make do with. You can always braid a fairly sturdy rope out of vines, especially if they're green. The only thing I don't have is a way to start fire but you can do that with a little fuzz, a rock, a stick and a shoestring.
If you have to survive something you can get pretty ingenious if you have to. The only thing is, if you are injured, it can be difficult.
