One time while working our way down the mountain I joked with a young, strong looking group of servicemen who were also hiking that the chivalrous thing to do would be to offer to carry my pack down for me..... one of them replied by offering to put it in the stream so I could pick it up at the portal....
I politely declined his offer and finished the trail with a dry pack.
Momma once saw a floating styrofoam ice chest in one of the Mammoth Lakes... it had apparently been chased in there by a bear... "No Bear not the Beer!" was said to have been the reaction of the fishermen...
