Or a different kind of tree?

I have used paracord in the past, and it worked fine. But I prefer to use a limb that's dead. Seems to be less friction there, and I hate getting pitch on my hands, because it will be there all trip long. But a simply 3/16 inch dacron cord will also work, and will probably be a little slicker than the paracord.

These days I use a bear canister. Some places require them...and now it's habit.
