This final note today, not, perhaps, what we want to hear in a season full of eating more than we should.

But the Washington State ferry system -- the biggest in the country -- has to cut capacity. Not 'cause the ships are getting smaller, but 'cause we're getting bigger. New rules from the Coast Guard say calculations should be made figuring an average passenger weight of 185 pounds -- that's up from 160.

No extra eggnog for me tonight.
