Hop the Keystone ferry and go over to Whidbey Island for the day. Coupeville is loaded with nice victorian homes, plus there's a great marsh for birds right at the ferry terminal on Whidbey. Several state parks around there, too. Head through Oak Harbor and go to Deception Pass. In Coupeville, have lunch (a big bowl of Pen Cove mussels and steamer clams) and a microbrew at Toby's Tavern, if I recall the name correctly.
My mind is drawing a big blank on the name right now, but there's a terrific Rhododendron preserve over there, too. Lots more flowers than rhodies, too.
edit- I finally remembered- It's the Meerkirk Rhododendrond Preserve, south (?) of the ferry terminal past Greenbanks- edit
Terrific sunrises at Fort Worden in Port Townsend, too. Lots of great architecure shots among the buildings at the fort, too, and a marine aquarium on the pier. Ships pass very close to the lighthouse, and the lighthouse isn't bad either, when you find the right angles. If you're into boats, also go to the wooden boat school in PT itself.
edit- See which weekend festivals or fairs are under way in PT, also. Locals note that PT has 52 weekly festivals per year, so there's always something going on.- edit
