The trail winds through the pines, the banks of snow covering it marked here and there by animal tracks. Among the black branches of the conifers to either side is the occasional dark bulk of a squirrel nest. To the northwest, lights twinkle through the pine needles, and the scent of a fire is discernible, carried on the crisp, wintry air.
