What's more scarier downhill skiing or downhill biking?
Biking would be my answer.
It depends on your ability as to which is "more" scarier. (Is that like "most" bestest?) Personally, neither of those scare me, but what DOES scare me is roller-skating or skateboarding down a steep hill.
Downhill biking. Snow is softer landing but there's also the chance of dying like sonny bono. -source road by bike down a hill at 8 broke my wrist and bloodied my face,
Skiing. Skis don't have brakes. Or a cup holder.
