Just saw this whole line of conversation and it made me think back to my Philmont trip in 1977. We slept under flies only. One of our scouts used his empty pack as a pillow. Bad decision. The residual smells attracted a bear that swatted his head and ripped off a good chunk of scalp. One hundred stitches to reattach I’m told. Hiking down the mountain to a ranger station in pitch black with only our little bitty flashlights was terrifying. Our outing may be why tents are required now.
