If you travel down to Ushuaia, Argentina, you might just find a bus plastered with a massive photograph of Sam Evans-Brown. In that photo, he's sprinting, shoulder to shoulder, with Olympic cross-country ski-racer Martin Bianchi in the final stretch of the 2008 national ski championship of Argentina. Today, Sam brings us the backstory to that photograph--a story about a split-second act of kindness that altered the course of Martin's life, and about figuring out when it's time to leave the races behind. Sam hosts the podcast 'Outside In', a show from New Hampshire Public Radio about the natural world and how we use it. A version of this story originally aired on 'Outside In'.
