On these snowy winter days, we have the opportunity to become more conscious of the paths of our fellow travelers, as sidewalks and forests alike transform into a palimpsest of footprints. In the city, a pedestrian might stomp a path through a sidewalk snow drift that is then gratefully used by other commuters; in the woods we can trace ski trails and boot prints to discover which trails are most traveled. A pile of rocks or a broken branch can indicate a suggested direction when no trail has been blazed: we must remember to look up as well as down! - caitlin van dusen
