Two Rivers musher Aliy Zirkle and all 14 of her SP Kennel dogs made it to the Iditarod Trail Sled Dog Race's halfway point, the Iditarod checkpoint, for her 24-hour layover. Other mushers coming off their 24s are expected through there Thursday. Earlier on their breaks, mushers shared stories of injuries, sled mishaps and wildlife encounters, as well as sled dog litter-naming conventions.
