Check out what a day is like for Darin Shapiro and his son, Kien. They get in a fun set on their System 2.0 and then take some runs on their mountain bike track. Kien is nearly seven and you can see that he is definitely going to be a shredder on the board and the bike. The soundtrack for this video was done by Darin, showing he's not only a legend on the water, but also a multi-talented musician.
