Here is almost everything
needed to hang 'em high. The only additional items you'll need is
a length of small diameter cord and a rock to toss. When you have
tossed the cord over the right branch just tie an end to the tree
rope and pull it up and over the selected branch and tie it off.
Do the same on a tree 15 feet away, snap on the packs and pull 'em
up. Kinda
like this.
