I got on a kick to see if I could lighten my food hanging cord and I discovered some new information. A number of people in old posts here seem to like mason twine. I will try that in spite of the reported tangles it can get. But I also ran across a prepared kit that contains a rock bag for throwing over the limb of a tree. Has anyone made one of those? It shouldn't be to complicated. I may put a cotton string attachment on mine so if the rock and bag get perminantly, accidentally, wrapped around the tree I can pull real hard and break the cotton link and retreave my line and bag. I also see they supply a "barrier bag" with he kit for oder containment. Do you use such a thing. I never have and have not had a problem camping where there are bears known to be the area.
