Amy Purdy lost her legs to a severe case of bacterial meningitis. Now she's the top-ranked female adaptive snowboarder in the U.S. and was a finalist on season 18 of “Dancing with the Stars.” She has a new memoir out, “On My Own Two Feet: From Losing My Legs to Learning the Dance of Life," and Ryan Warner will be interviewing her Monday night at the Tattered Cover on Colfax Avenue in Denver. We thought we'd post a few videos of Purdy in action.
