The first year I competed in the BAKER banked slalom, a guy from Canada I believe had this deck not much bigger then a skate deck with bindings, but it had two approx 4 foot long twin tipped ski's that were mounted side by side, that you rode like a snowboard, tried to Google it but couldn't find it. The guy actually finished in the top 5.
There was a guy from the BAKER area that invented a chainsaw driven snowboard. They did a show on him on one of the local shows, all he could do was ride it on flat groomed telemark trails and the skinny skiers hated him, they were going out for a peaceful trip, then here comes 2 stroke snowboard guy
