Three in the morning, a clipper down out of Canada, and Golf Road is one set of taillights heading the other way. Snow Warriors Snow Removal & Services LLC is out in it, plowing lots and driveways, shoveling the steps and walks no blade can touch, spreading salt where packed lanes would otherwise glaze over by first light. Schaumburg holds a remarkable amount of pavement for its size, and every acre of it belongs to somebody who has to open at eight. The measure of a night's work is an entryway already clear when the first key turns in the door, and a driveway a car can back out of without a second thought. Snow arrives on this flat country in a hurry, so the answer is to be there while it is still coming down.
