Seaford sits on the Nanticoke River in southern Delaware. It was once called the Nylon Capital of the World because of a big factory that made this stretchy material.
You can watch boats on the river, visit the Seaford Museum to learn local history, or paddle a canoe on the calm Nanticoke waters. Bald eagles sometimes soar overhead.
This wide, calm river is great for fishing, boating, and paddling. Herons, ospreys, and even bald eagles make their homes along its shores.
Seaford earned the nickname Nylon Capital of the World when a large factory here made the material used in everything from stockings to parachutes.
