This is one of the things I love about the Survival Forum - it makes us THINK, sometimes in odd or impractical directions, but it makes us use our minds and evaluate what we think we know, or are relatively sure of, in different ways and in new lights. I know that I personally have read about and absorbed more ways to use a garbage bag, a bit of string and a razor blade then I would ever have believed possible. Are some of these discussions and "what if?" scenarios off the wall? Sure they are. But one thing I have learned in my brief time on this rock is that when Mr. Murphy comes calling (and he has EVERYONE's number, whether it's listed or not!) it is never in a way you anticipated, let alone expected.
