My home is awash in snow now, and it will be here for weeks. It fell and fell, and now there are canyons we drive through, peeking around the corners. Yesterday I was skiing over the snow next to a lake close to my house. The ski paths have two parts. To the right, there are a pair of grooves. Next to that is a broader area, flattened down into a broad snow road. They accommodate two different kinds of Nordic skiing: to the right (in the grooves) are the "classic" skiers, and to the left are the "skate" skiers. The styles are very different. I am a "classic" skier, which means that I trudge along in the tracks. Well, "trudging" isn't the right word, exactly, when I am doing it well-- instead, it is step and glide, step and glide, hearing the little whoosh of the snow beneath me. The skaters are different: more elegant, faster, and rhythmic. A small group of teens will whip by me, striding in unison, like a little flock of birds taking joy in
