im not sure if you do chinies down hill by the same rules as me but i do it as you start out about 10 yards away from your skies that are lined up in a line then you run jump into them and then its a full contact race to the bottem its so much fun i like to do it on those long ass greens that just go on forever i think it makes it more fun
i've never entered one... mainly cos' i'd probably attempt to be competative and wreck myself on some other nutter.
the one i saw was just on a huge steep bowl and it was pretty much a straight line race for the winner and all the idiots in the middle killed themselves turning into each other at mach 20. start in the bindings and it's full cotact although only so much as if you hit the back of someone cutting you up you can both enjoy the other hundred or so competitors spearing you with their tips!
