In our journey along the coastline we needed to get from Lewes, DE to Cape May, NJ. Not overly excited about NJ, but it was in the path so off we went on the Cape May Lewes Ferry. This ferry is much larger than NC ferries holding about 100 cars and 800 people. We arrived without a reservation and easily made it on the ferry. Unfortunately it costs $52 one way! The ferry had 3 decks including the auto deck so there was plenty of room to roam about. With the tropical storm coming the seas were at the fun stage.
