Maddie Pellman, from the Who Runs This Park? podcast, drops in to exchange exceptional guests with Doc. Settle in and buckle up as both Doc and Maddie (good smelling Hiker Trash), share some of their favorite guests and stories from their podcasts. Have your pens ready because there may be some college credit available at the end of this episode. Maddie covers three different National Park superintendents, while Doc covers an exceptional expeditionist, an unbelievably thrilling finish to the world's toughest race, and an epic cyclist. You won't be disappointed.
