remember that you have to be in the salt except for the Skagit. The other rivers are closed.
Im not much of a cutt fisherman, but from being around the beaches out here, I think that Kayak point would be pretty decent.
Im sure that someone else out there has some better info, but I would try Kayak point if I was going to stay up in this area.
I am going to try Carkeek Park this weekend, have heard decent reports lately about it.
