If you're looking for some free videos on snowboard tricks, I've made a series of free snowboard trick videos. They cover all kinds of tricks from backside 180, boardslides, frontside 360's, and many more. I've been teaching snowboarding in Whistler's Ride Tribe program for the past ten years. I'm adding new videos all the time, and taking request for future videos.
