Brattlecast #45 - John Ledyard's Voyages
He voyaged with Captain Cook, escaped from college via canoe, and attempted to walk across Russia. But, most importantly for our purposes, he also wrote a plain looking, easily discarded book, some volumes of which contain an extremely valuable map. He's John Ledyard, the most interesting New England character you've never heard of and the author of Captain Cook's Voyages, the book we should all be scouring yard sales for!
