An Edmonton veteran has taken up paddle boarding as a way to cope with post traumatic stress disorder (PTSD). He's paddling along a fur trade route from Edmonton to Winnipeg in a journey that will take a month and a half. This CBC article explains why he's doing it and how paddle boarding helps him manage his PTSD.
