For those of us that live in a northern climate, the first snowfall is often a wondrous event. School children leap from their desks to gather at the windows, amazed at the fluffy, giant flakes that drift to the ground, slowly turning everything pristine, pillow soft, and white. Invariably, a few radio stations can’t resist playing “White Christmas” for a sentimental caller or two, and for one quiet afternoon, it’s Americana, as captured by a Norman Rockwell painting.
