My hunting buddy's granddad would routinely take the train to hunt ducks. Other than by boat, it was the only way into his abandoned rice fields just outside of Savannah. (Also the haunts of market hunter Ward Allen, another story) And the story is that Boykin Spaniels partially owe trains to their origin. Trains were the easiest way into the South Carolina swamps that transected them. Hunters there used small duck boats that would fold up and one man could easily handle on the trains. The small boats required small dogs for stability. Necessity was the mother of the Boykin's invention.
