It’s Tuesday, and we have a two-fer on dog profiles here on the Iditapod. And as we anticipate Norwegian musher Thomas Waerner winning the 2020 Iditarod Trail Sled Dog Race in Nome early Wednesday -- barring any unforeseen changes -- we have a story about the modified Shaktoolik checkpoint, a remembrance of an all-star volunteer checkpoint leader in Unalakleet and a little about how a major, longtime sponsor of the Iditarod has announced it’s pulling out. (Maybe not all in that order).
