There are a half dozen public areas out there. Depending on the weather and the crowds any one of them can produce a nice limit.
Avoid Jensen access. Too many people shooting too high, not enough birds. The Welks Unit can produce well if you get a pond and there are not too many people out there. I've done well at the Skagit Flats if you want to walk.
Take a few decoys, set up and see what happens.
