Not terribly. We've seen catches in recent weeks out this way as well. Some streams it's pretty common to see them late in December and have even seen them caught in mid-February. I also seem to recall a picture of herzog's some years ago of a monster silver out of a Humptulips fork that I believe was caught in late February or thereabouts. I've caught kings carrying lice through Christmas eve and dark jacks after the first of the year. Another guide out here caught a chrome king out of the Bogachiel in the the last week of January about ten years ago.
