I saw Cliff at Canoecopia this year and I was impressed. This is knowledge born of experience. You could camp your whole life and never pick up these skills.
On my own I never would have thought of the potential of a tarp. Now my eyes are open, it's probably the next camping purchase I'll make.
I found this video thought provoking and enjoyed all the segments. It could have been longer, but it was definitely worthwhile. No matter how long you've been camping this video will teach you at least one new skill.
