I was thinking about the etymology of 'piggyback', and whether the animal pigs ride each others backs, having never seen it.

Thanks for those with direct experience on farms etc. Good gags too.

    Stuck fast, upside down in a narrow pass in a cave.

    This is from a real incident, where someone perished. They were an expert caver.

    I can't look up the story or read about it again.

    My heart goes out to that person, their family and friends. Just one of the saddest events.
