Some tips for hanging a bear bag:
What I found for myself is that a rope over about 40 feet is more than I need on the AT and the extra just gets tangled up!! Nothing worse than a tangled bear rope.
Reflective is a good idea.
One thing I discovered that is very helpful is “tying” it in a daisy chain for storage. Otherwise, it just gets tangled!
Not only that, I also learned to not tie a rock to the end of the rope when tossing over a branch. Why? Because eventually, the tied rock is going to spin around the branch and be impossible to get down. I have seen many partial ropes dangling from trees. Just wrap the rope around the rock a few times. Yes, it falls off sometimes, so I gather two or three rocks. Maybe there’s a better way, but this works for me.
