This seems to be a theme for Pseudopod recently, with 631 and 633. I also find it rather funny that, as I write this, Spotify apparently seems to find fit to queue up "The Wreck of the Edmund Fitzgerald" to listen to.
I don't want to listen to something like this every week, but every so often, it works. This was a good story. I quite enjoyed listening to the story and letting my own imagination run away with those pieces of scrimshaw.
