a seasonal tip...HOW TO SURVIVE A RUNAWAY SLED

-slow the sled using emergency sterring and breaking. move side to slide to reduce speed.
-redirect the sled. turn the sled into a course that traverses the hill, if possible.
-roll off the sled. perform a single side-ways roll off the sled. continue rolling until momentum slows and you are on your stomach.
-dig the toes of you shoes into the snow. draggin [if head first] or digging [if feet first] with your toes to slow your descent only works on powdery [non-snowboarded] snow. if you are on hard-packed [snowboarded] snow, do not dig your feet while sliding or you risk flipping over.
-use your hands. dig your hands into the snow in a "dog paddle" position. if you are sliding head first, this will cause your legs to swing around and you will be descending more safely feet first. avoid running into trees and do not grab stationary objects: an abrupt stop may dislocate a shoulder.

be safe, folks.
