I knew this guy and his family when they lived in Pensacola, FL.  I think Sierra was about 12 or 13 years old so it makes sense that he didn't drink or anything thing.  But, knowing him then made me think it was totally possible that he would become a professional skateboarder.  I've never met someone that was more dedicated to spending 23.5 hrs a day on a skateboard.  One night my friend Paul and I were at a party and from the balcony we could see Sierra skating some terrible bench spot by himself in the middle of the night.  I am glad that he as loosened up a little bit and embraced the fun side of life.  There has never been a more serious 13 year old.  Sierra is a good dude that deserves everything good that he gets in life.
