The Bainbridge Island - Seattle ferry not only carries people and vehicles between those communities, but is also a community in itself. Above these 2 vehicle decks are 2 passengera decks. There can be a few thousand people on board during peak hours or when there are Mariners or Seahawks games going on.
Most of the people who ride the ferry are regular commuters with very fixed patterns and habits. And those patterns can be pretty firmly set. For example, the other day I said Hi to a friend who I often chat with on a morning ferry... but this time we were on an evening ferry. It actually took him a moment to recognize me!
This is a view from the western end of the ferry "Wenatchee" as we head toward Bainbridge Island. Way back at the other end of the car deck you can see a little slice of Seattle framed up. The crossing takes about 35 minutes and is a very popular tourist activity - kids love it! You get a lovely view of the Seattle skyline, and there are lots of nice places to eat lunch or dinner on Bainbridge within easy walking distance of the ferry terminal.
