Each Memorial Day weekend, artists and activists, filmmakers and photographers come to Telluride for Mountainfilm. At our core, we are about exploring, preserving and sustaining environments, cultures and conversations, so this unique gathering is part film festival and part ideas festival with leading edge thinkers – and doers – getting together to change the world. Leading up to this year’s festival we wanted to focus on conversations worth sustaining and we’ve asked some of Mountainfilm’s special guests to help us out. Throughout the coming weeks we’ll be posting our conversations with them. We hope that they engage and inspire you.
