Last time I was quadding after smokin a fatty I hit a witches eye and had it not been for my chest protector I would've broken a few ribs for sure, I laid on the ground for 30 mins gasping for air, and I ride a raptor 700 that because of that accident now has a broken light and bent plastics, battle scars haha! Morale of the story is not don't smoke and quad, its always wear your safety gear!
