I would set up a camp, get a nice roaring fire going, get them comfortable. Then I would slice my arm, just enough to get a good blood flow, which I would let soak into a piece of cloth. I'd properly wrap the arm, then take the bloody cloth and hang it up a few feet off the ground behind the camp, just enough so the scent could waft down wind. Then I would sneak off and run for freedom, leaving them there.
If you've ever seen "The Edge" you know what happens next.
spoiler alert!
