The virtues of having a camping tarp are obvious when it rains, but you may not realize that it's really nice to have one even when the sun is shinning as the tarp will provide guaranteed shade as well. At night, being under a tarp will result in a temperature increase especially if you have a lantern going. You can also situate a tarp as a lean-to if you need a wind break just by staking one side all the way to the ground. The real trick to a tarp is getting your rope high enough so the tarp doesn't sag too low.
Locate a couple of trees the right distance apart with basically level ground in between them. Coil about 20 feet of rope and simply throw it up over a limb 12 to 15 feet high.
Walk the rope around the tree tightly, two to three times.
Tie the rope to itself or a lower branch or even another tree.
Giving it a good tug. It will have to hold the tarp even when the wind decides to gust.
Throw the rope up over a good limb on the other tree but don't tighten it yet.
Walk the tarp over the rope so it is pretty much centered.
Secure the tarp through the center eyelid to the rope at both ends with a small piece of twine or a wire tie.
Lift the tarp tight, then wrap the tree and tie as in steps two and three.
Tie twine or small rope to each corner eyelid and
about six to eight feet away or tie to another tree or bush if available. (Use whatever you have.)
Drill a couple holes in a piece of wood. (Obviously this needs to be done at home.) The tension is adjusted by sliding it up or down the rope.
