Think so?
Well I can tell you that the lean to that is described in most army manuals will not work but yet it is still on this site.
I guess I am the only one who has actually made an expedient shelter that turned rain. Because if your still pushing that information you have never spent the night in one.
In my opinion discussion is one of the ways you hone your knowledge and skills. If you will go through most survival manuals you will find some good info and some nonsense.
Now wouldn't it be better to talk about our experiances just in case your stuck in a freezing rain sometime and have the experiance of someone who has been stuck in a similer situation?
Or perhaps Grey Wolf you know things that I would like to know that will only come out with some discussion. You might be sitting on a little information that would be valuable to me that seems so common to you that it never gets posted.
I would say we all have different experiances that would be valuable to each other even if we have been through the same things.
