I came across this the other day and couldn't make up my mind about how I felt about it. In a shelter, there was a new/sealed Mountain House dinner hanging from a rope, and then in the PVC tube there was a couple new/sealed packs of crackers, bars and a bag of pepperoni. It looked new, but who knows? Is that someone on their last day leaving what they don't need and hoping someone else will use it, or more likely someone dumping off weight and leaving trash for someone else to haul out? I've never seen it before and not sure how common/accepted this is.
