just got back from come camping in the smokies where the mice got into my food sack again. I had been just hanging my silnylon food stuff sack from the pulleys. lately i started to use a baffle made from a cd to get in their way between the bag and the pulley, attached to a rope, but this has failed as well. I talked to some other guys camping at the same site who hung their entire pack up, and just covered it with a garbage bag. they said that they have never had mice get their food, and they definitely didn't last night. I'm wondering if maybe the mice can't smell the food thru a backpack? I hate to try this though, and wind up with holes in my pack because of it.
