So...and I'm guessing they are not getting rear ended with their tobaggans? That is what I liked about the poles. It seems to be more functional for up and down terrain, keeping whatever you are pulling away from your body. The video short of igloo Ed comming up and over the fairly steep rise is a perfect example of what I am talking about. I'm thinking, without the poles, the pulk would be temporarily out of control.
(Thinking)...of course if the toboggan is that heavy, you would not be dragging it in that kind of up and down terrain. Then it might be dogsled time. But, one small step at a time...
