Snow settles differently on a cul-de-sac — it arrives in a circle and it has to leave in one, and the driveways off Book Road all pour into the same little turnaround. Kevin's Snow Services keeps those streets open: plowing the drives, shoveling steps and the approach to the mailbox, salting the slope where concrete meets apron. On a good night the whole route is headlights and heater and a thermos, house after house, and the neighborhood never hears a thing. There is a plain pride in pulling away from a place knowing the car will back out straight. Naperville mornings start early, so the work has to start earlier.
