Ray, a gentleman I met in Gitwinksilhkw, northern BC, rigged together this system behind his mom's house. He fishes down by the bank, and loads the fish into what I guess is a Rubbermaid container. Once it's filled up he walks up the stairs he's built, and retrieves the fish-laden container with an old electric winch.
"I got tired of packing the fish up those stairs all the time," he said.
In a world where fish are disappearing from streams, a lot of people would rather enjoy that kind of problem. Still, it's a problem elegantly solved.
