I found a terrific place for all kinds of related information. Its a post at The Survivalist blog. I have a link to his blog in my links column to the right and if you click on this posts title it will take you to that article. As always, no matter how many books or how much stuff you read on the net, unless you actually do it hands on its worthless. Once you build a fire from a bow and drill or make cordage from dogbane, the skill sticks where it counts. In your head. Practice, practice, practice!!!
