DENVER (AP) - For years, daredevils climbed atop their snowmobiles, sped them up icy ramps and flipped them head over heels into the frosty night air. Fans of action sports cheered while others wondered whether the sport was a good idea.
It's a question getting more serious look after last month's Winter X Games, where things went wrong in a tragic way.
One rider flew off his vehicle and the machine went careening into the fence, dangerously close to spectators. Another wrecked and separated his pelvis. That rider's brother, 25-year-old Caleb Moore, lost control, landed on his head and, four days later, died from injuries related to the accident.
Authorities are now discussing stricter permit procedures among other measures to improve safety.
