Describe Jonas' experience with snow.

When given the memory of snow, Jonas at first shivers, and then realizes that the air is frigid. In the memory he is sitting on a sled at the top of a hill. He has never actually seen a hill, but he instinctively knows its name. As he speeds downhill, he is delighted by the sensation, but as he nears the bottom, the sled slows down, and although he pushes to make the sled plow through the snow that has built up, eventually he finds that he must stop. Dream over.
