VIBE Outside Youth Conference

This November, MAC students are organizing a youth outdoor leadership conference, and we’d love to invite any high school aged youth to join us. What makes this event special is that it’s entirely student-led and student-driven (with adult speakers). A youth committee has designed every aspect of the conference—the name, program tracks, flyer, schedule, and speaker lineup.
