Extreme Sports

The beachfront city of Malibu voted Monday to outlaw a form of youthful daredevilry known as speedboarding -- an extreme hobby that has grown increasingly popular here. Speedboarders don protective helmets, knee and elbow pads, and sometimes even sleek bodysuits before hopping onto long skateboards and rocketing down steep public streets and canyon roads at speeds greater than 40 mph. Enthusiasts swear by speedboarding's addictive adrenaline rush.
