If you find yourself lost in the woods, hug a tree. Eventually a clearcut gypo logging operation will show up and have you peppersprayed. We are all burdened with falsehoods in survival literature and folklore. I'm still trying to find a anthropological reference to Apache Debri Huts in Arizona and identify the military researchers who came up with magnesium bars and solar stills. Whoever illustrated the first survival tome should be suing every other publication for copyright infringement of that neatly latticed debri shelter. I suppose they are to embaressed, another infamous trap drawing so obviously wrong even a retarded chipmunk could see it will never work. Survival is as much stoic humour at all the nonsense and hype as real experience. Do what the Inuit do and get some sleep. If it's a zip together WIGGY unit you can invite it's detractor to crawl in with you and find out together. Hopefully it isn't Les Stroud, Cody or me. I hear tell we aren't afraid of bears because our heroic snoring scares off any beyond even a STORM whistle's maximum effective range.
