I believe the wire brush bristles from the rotating sidewalk sweeper have been dropping out of the drum. They are scattered all along the sidewalks. My child first alerted this to me as she picked some up on her way home from ADL (and cut her finger on them). Since then, we have been collecting them from all along Rivendell, Brickyard, Beech...wherever we see them when walking. I am concerned that if people are not notified of them, that either a younger child or pet could hurt themselves or that a lawn mower in the spring could be damaged or cause harm to another when they are struck.
