Cool footage of a four-year-old snowboarder hitting box slides, rails, jumps and cliffs on a mountain in Utah, USA. <br /><br />The video, filmed at Snowbird by the boy's father over Spring Break this year, shows little Terje taking to the slopes for his third season and performing a series of tricks. <br /><br />His mother later wrote online: "Terje also loves to skateboard and has been taking karate to help his focus. <br /><br />"He has been on a board since he could walk and his skills show it." <br /><br />"When we go up we just kind of have fun; he likes to do it," she continued. <br /><br />"His father points out little things that he can do and he just goes for it."
