I"ve been hammock camping it up for a few years now and I've got my system pretty well squared away. I'm not exactly up and up on the lingo that is used around here. I think I'm using what you all refer to as a ridgeline to hang my tarp with... but I'm getting the impression that some of you if not all of you use a 'ridgeline' underneath your tarp for something, which is where I begin to get confused... What exactly is the point if that's what is being done? A buddy of mine just got a hennessy that has a line running inside of it and I was completely baffled as to what it was for.... Sooo, am I missing out on something? What do you use that for?
