I watched this series when I was obsessed with the Iditarod, and it gave me a lot of information while writing a realistic fiction story about a woman who chose to participate. There is barely any swearing, though bleeped out when it is. For anyone who says that the Iditarod should end, just know that these dogs were literally bred to run. The mushers know the precautions of racing, they know the danger that they could face, yet they choose to do it. And the Iditarod is much better handled than it has been in years, with nearly 80% less dog deaths for a long time and much better care and more specific rules.
This was very informational and interesting to watch, and though slow in parts it was still amazing by my standards. It helped me so much with the book I was writing, and gave me a lot of interesting facts that I never knew before. I really wish there was more content like this in the world.
