Force via rope.

There are many knots that Scouts will find useful but there are a special few which allow for variability that makes them especially good to know in camping situations.  The "Trucker's Hitch" is one such knot and it is especially useful for tasks such as securing guy lines for tarps and shelters.  Since this knot requires the working end to be doubled-back through a fixed loop (similar to a pulley) such as a "Directional Figure-Eight" or a "Slippery Hitch" it allows for the application of extra force on the standing end of the line.  Watch the video to see one way this hitch can be tied.  Try finishing the "Trucker's Hitch" with a "Taut-line Hitch" to allow for control over the line tension, a "Slippery Hitch" (as show in the video) to allow for a quick release or "Two Half Hitches" for the most security.
