When we were first planning a day trip, our intention was to spend the day touring a couple of the San Juans, but looking at the ferry schedule, we realized that's not really possible - the schedules for the different islands don't really line up to allow you to visit more than one in a day. We were glad we decided to go even though we'd only get to stay in Anacortes. It's beautiful, and we chose a beautiful day in late August 2010 to enjoy the views!
It's too long ago to really remember what anything was called, but this was a state park that had a boat launch, so we headed there to be near the water.
And a meatloaf sandwich. We ate outside, in the sun, while people watching. My favorite!
We drove to the top of some place (dang, I wish I remembered what it was) for some more views.
