S7E4: Hot doggin' and leapfroggin'

Iditarod teams are contending with warm weather in the thousand-mile race, many choosing to run in the cool of night as much as possible. We'll talk about that in this episode, plus a little about what other sports some mushers have participated in outside of mushing. We have another Dog of the Day -- this time, a trusty leader named JoAnna -- and, as always, a listener question.
