31F, pea-soup fog. Passed 2 not-fully engaged bikers; one pounding the 'cross' button while not noting the 'walk' light, and the other turning left from the right-turn-only lane (that one is kind of an esthetic as well as legal faux pas 'cause there's a sensitive sensor in the actual left-turn lane; also he was forcing right-turning cars into the bike lane to their right).
