Driving up the south fork of the Kentucky River when it was dry, Marion Post Wolcott had to be pulled out of a creek by a mule, then later hauled out of the sand, and finally had a flat miles from everything and no jack! She found help and borrowed a fence post to prop the car up while the flat was switched with the spare. That's using whats available, a little basic leverage, and lots of sweat to adapt, overcome, and innovate. http://www.shorpy.com/node/3464?size=_original
