The sled dogs went wild after they all got harnessed. They jerked the sled so hard pulling because they are ready to go! The sled was tied to a tree until a person came and untied it. They go so fast that you have to hang on and keep your feet on these skinny 1 - 2 inch runners. The noise is deafening and suddenly you are flying through the snow silently with just the hiss of the runners! Fabulous!
