He is good. He's from the Morgan Hill area I think. You can see him in Delta Sessions. He rode a Double Up prior to Crown, and a Funded Tech board, prior to that.
Derek Cook is a very styly rider. He does ticks with a lot of flare. I think his batwings are the best anywhere. He is very fun to watch because he has a lot of fun riding.
You can watch www.westsideconnection for his pics and videos all summer. He will have a full section in DS2. I picked him as rookie of the year last year as he learned more in one season than anybody I have ever seen. Always smiling and always learning!
