In my tent days, I always kept my gear under a vestibule. I've watched probably 30 of Shug's videos and I know he carries some kind of ground covering and puts his stuff under his hammock.
So my questions. What are the options? If rain isn't expected, can I hang my pack from my tarp ridgeline (on the tree) or the hammocks tree strap with a a-biner? I'm not sure if that makes sense. But thanks.
