So I was riding along a multi-use path with a wall on one side and chain-link fence on the other. The squirrel saw me coming and ran towards the wall. Dead end. He darts the other way and hesitates at the small openings of the fence. Worst choice of its life: it darts back into the path, and directly under my tires. I look back and see it flopping around, so I turn around to check on it. Fortunately the little guy looks stunned but not seriously injured. That was the largest living thing I've run over so far. To make matters worse, it started snowing big time on the way home. Glasses fogging up, snow pounding my retinas, brakes becoming worthless in the wet. What a day.
