Some nights the International Bridge lights blur out completely and the only thing moving on Portage Avenue is a plow. Tangerine Tiller, LLC takes those nights — clearing drives and lots while blowing snow keeps rewriting them, shoveling the steps and the path to the door, laying salt where ice sets up hard against the cold coming off the river. March here is as serious as January, so nothing about the season gets called early. There is an art to where the snow goes: never in front of a door, never where it will freeze into a wall by morning. Handled that way, a Soo winter stays livable.
