Bear.
I remember a bear came in to our camp once and trying to get to our stuff. My brother pulls out his pocket knife and I say “What do you expect to do with that against a bear?”
He answered “Bear?? It’s to cut a hole in the back of the tent if he starts heading this way!”
It was a black bear and we scared him away with shouts and banging pots and pans. About every fifteen minutes afterwards we could hear the same thing as he made his way to all the campsites along the lake!
