Remember B.Y.O.D.T. In less than an hour, with less than one roll of Duct Tape, you can have your own hammock to sleep in instead of on the rocky ground.
Even better, though, you can take it with you the next day because it only weighs 1lb.

Some string may be handy to help hang the Hammock while you are building it.
Step 1: Creating the frame
To create the center support double over (see next picture) a piece of Duct Tape so that after being doubled over it is 1ft longer than your height with an additional foot on each end. The total length of the center support should be your height + 3ft.
The side supports depend on how wide you wish to make the Hammock. In the picture I have them extend about 1ft from the center support on each side. Keep in mind that by increasing or decreasing the side width it can shorten or lengthen the side supports.
Make sure that the ends of the 2 side supports and 1 center support respectively meet at 2 intersections which are 1ft from each end. This will be important for the next step.
