Very brief profiles of the exuberant young athletes provide perspective on what sort of person would go rocketing down cliffs on a snowboard. "The feeling of fear turns me on," says one female high mountain snowboarder. "I don't feel any more happy than when I'm laying it on the line." This is a visually arresting and highly entertaining look at snowy sports that seem designed for a video extravaganza. In addition to the coverage of competition, a selection on the DVD aptly titled "Chills/Spills" contains about an hour of rock accompanying reckless stuff on skis and snowmobiles you don't even want to think about doing at home. --Robert J.
