Over two centuries ago, a sea serpent showed up in Gloucester Harbor, swimming and playing and splashing in full view of the townsfolk. It’s one of the most well-documented sea serpent sightings in history. But what was the mysterious creature?

Off the Plank: The Great Gloucester Sea Serpent

For Davis Dunavin, being a journalist is a little bit like being a cross between a wandering storyteller and a detective. For nearly eight years, he's set sail to learn about pirate history, hiked the Appalachian Trail, spent the night in Lizzie Borden's house and browsed the books in Mark Twain's library, all in search of the hidden stories buried in everyday places across the Northeast.This season on Off The Path, he digs deep to explore the origins of things that are ubiquitous, Teddy Roosevelt, the tuxedo, the first video game, as well as those stories we think we already know, like the first airplane flight or stories that aren't as well-known, like the beginnings of the artist behind the Barack Obama “Hope” poster. But every single episode involves an element of surprise, an ironic twist or a fascinating connection you might not expect when the story begins.
