One thing I love most about living in Washington State is that we're literally surrounded by water. I love just sitting at the beach and listening to the waves crashing, I love running around and taking pictures while the kids play, and I love exploring all the islands around us. And, while I wish we had our own motor boat to make island hopping easy, I do love the inherent adventure in hopping on one of the Washington State Ferries and taking it somewhere for the day.
It's great because you can just walk on with your day's worth of stuff and let someone else take you where you want to go, let them figure out where to park, and they can provide bathrooms, snack options, and entertainment.
