Are you people out of your minds!?! The last thing we instructors want is another distraction on the slopes. Recreational boarders and skiiers have little enough skill as it is. They have more than enough to handle and still finish vertically.
And don't try to tell us only experts will buy them. If they were experts they'd be instructing too.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
