Cobb Powder Horn

Almost a hundred years ago in Bemidji, MN, 10 year-old Joseph Burns wriggled his feet in the mud and felt something solid. He reached down and pulled out a powder horn engraved with these words: For Captain Richard Cobb-1762. After all these years, Joseph’s son Robert takes his question to host Gwen Wright: Who is Captain Richard Cobb and what is the story behind this horn?
