i see tons of much potential for highway overpasses.
if you see an overpass (off to the side of the road or highway it travels over) that has been built up with earth so that there is a steep slope on both sides of the overpass, i think there is tons of potential to gap that section of road. a jump could be built on one side of the steep slope, and the other side also has an equally steep slope as a landing. a skier could be towed in, and easily gap the overpass.
just to put an mage in your head, the skier, when bein towed in, would travel on the very left of this picture, and gap the section of road just before the bridge.
hope i didnt lose you all, but i seriously think it would be the coolest thing ever...
