In today's episode of Backpacker Radio, we sit down with Teresa Martinez, the executive director at the Continental Divide Trail Coalition.  We talk all things CDT, including the future of the trail, the biggest threats to its continued development, Teresa's favorite stretch of trail, and way more.  We also talk through some layering strategies for the Appalachian Trail, and Chaunce gives us a primer on vlogging etiquette.  We close out the show by featuring your questions via Instagram.
