I've been seeing daffodils and crocuses in neighborhood gardens, heather has been blooming a while, and there's been plenty of bird song. There's still a while before the tulips bloom, but it's coming.

Can anybody recommend a route to ride by a lot of tulip fields? I'm planning to take a day off mid week and head up to the La Conner area. But I don't know the area well, don't know which fields are flowers vs anything else, etc. I'm not looking for an organized group ride, just a route to follow. If I had to choose today I'd want something in the 30 to 40 mile range, but I'm open to longer.
