Looks like you just need to go faster. If you never slow down, you never get stuck! If for some reason you do have to stop say for lunch or to figure out where the hell you are, I sugjest doing so on the top of a large cliff, right on the edge, with your skis hanging off. That way you can get going againIf you are in a flat area with no cliffs I would advise stoping on the top of a large tree. For instructions on how to park on top of large trees you will have to PM trailtoy1993 because he seems to have it down? If there are no cliffs or trees then there is no reason to get stuck in the first place.
I wish that worked all the time. I remember a day a few years back on Grand Mesa where my piped 800 with a 151 couldn't maintain speed trying to cut fresh tracks
