I want to know the answer to the following question:
What organization runs the largest line of ferries in the US?
All the background I'm provided with is that "Washington State Ferries, which manages the largest network of ferries in the United States and third largest in the world, connects Seattle to Bainbridge and Vashon Islands in Puget Sound and to Bremerton and Southworth on the Kitsap Peninsula.". Is that enough to answer the question?
