Snoqualmie's park is icy as shit, the rails can be sticky, and there are usually a bunch of kids--who think they are really good--cutting people off as they try to drop in. That being said, the park crew regularly makes some fun features, and every once in a while you see a cool trick get thrown. I watched people hitting that jump the day they filmed this, and it was some of the best skiing I've ever seen outside of Colorado.
All I can say is, props for trying a dub on the "large" line.
