When it comes to biking on the road, Jenni Gaertner rides by the rules. She straps on a helmet, wears reflective clothing, goes with the flow of traffic and is as unassuming as the vehicles that travel with her. That’s why Gaertner, on a recent Sunday ride from her home in Coeur d’Alene through Liberty Lake and Spokane Valley, broke down in tears after three separate episodes of harassment from passing motorists. One incident, in which a man suggested she wouldn’t win a fight with his truck, prompted her to memorize the license plate and report it to police.
