So I have a sled deck because I live in ak and its very convient. I don't have too many issues with loading it as long as I kick about an inch of snow on the ground at the base of the ramp, but the girl just can't seem to get it down and I can't always do it for her. In a sledding magazine at one point in time I saw a ramp extension that was a track wide and laid on the ground hooking to the bottom of the ramp so that you could just crawl up it instead of having to hit it hard enough to slide far enough up to make the track catch. Does anyone know what they are called, where to get one, or if they work like they say?
