So, is a kilogram more or less than a mile? I guess I never got that.

I've never really lucked into a nice place to hang stuff, but have tied things off like you describe. Sometimes I have a cleanish tarp to set meat on if I can't get it straight in a game bag. I cut up a moose by myself, but it must have looked a lot like a UFC fight that I was losing (and I had the knife).
