John Shewey wrote the book mentioed above. Also, there was a good article on Surf Perch off Long Beach in the Spring issue of NW Flyfishing. I've heard that the mouth of the Copalis Riv. is good for perch, as is the new diversion jetty between Tokeland and North Cove (south of Westport). I'm not sure, but I thnk spring is the best time to fish them. That is when I see the most effort off the beaches.
