Endless trees along the Iditarod Trail (Zachariah Hughes/Alaska Public Media photo)A lot has happened since the last podcast: Willow musher DeeDee Jonrowe has scratched in her 36th Iditarod, which she said would be her last. Meantime, front-of-the-pack mushers are taking their 24-hour layovers, so this is a good time to talk about how times are adjusted to correct from the staggered, every-two-minute race starts. Plus: More off-trail drama related to dogs and drugs! Sheesh! We talk to a fellow Iditarod reporter about what has been described as a confrontational encounter between the race’s head toxicologist and a musher right before the official start on Sunday.
