It is not easy to first try to carve a path with your toboggan. To glide easily down a slope, a path must be forced into being by repeated attempts to slide down the hill or by tamping down the snow with feet and shovels. Waxing and waning with time, the white noise of the storm is the background against which your mark is made; if the path is not maintained, it will get covered again. Once created though, attempts to slide down beside your path in some different way will be easily deferred to the original lane unless you purposefully create a more definite fork in your course.
