I think my favorite from the photos, paws down, is the Wallace and Gromit entry (also here). Rowing along on top of a giant sunny-side-up egg, even! Smashing.
The black rat (also here), a traditional participant along with the pink poodle and giant frog, made a triumphant return. And a special hats off to the rowing Elvises, winners of the Grand Mediocre prize (for finishing in the middle of the pack).
Next up: Arcata's KSR.
