Girdwood's Nicolas Petit stayed in the lead of the 2019 Iditarod Trail Sled Dog Race on Sunday after making a long 90ish-mile run from Kaltag to Unalakleet overnight. We hear from a couple Yukon-Kuskokwim-area rookies in this year's race, and a couple YK-area parents with kids in the Iditarod. Plus, a question about climate change and a conversation with Iditarod musher Kristin Knight Pace, who has a book out called "This Much Country."
