Hiking guide and outdoor adventurer Tracie O'Brien drops into the studio from the Southern Hemisphere to talk trail with Doc. Settle in and listen up as the soon to be grandmother shares some adventures, including some discussion of the Great Ocean Walk, an angry King Brown, the joys of one-poling it, dueling dingoes outside the tent, remote first aid, and the transformative experience of hiking the extremely difficult Kokoda Trail in Papua New Guinea.
