u gotta realize sledneck nation (wyoming, montana, north dakota, minnesota, wisconsin, michigan, and others) is cold, snowy and flat and these people have nothing else to do other than snomo, so they probably boost the ratings like 209873965%. And that's why backflipping a snowmobile is more important to ESPN than an insane pipe run, even though we all know how much more important skiing is in the action sports world, it's not as important in the $$$$$$$$$$$$ world.
I completely agree though, it makes me go crazy.  Same with motocross in the summer, and basically no coverage of Skateboard Street.
