By November the DuPage River runs cold and clear through Channahon and the mornings arrive with frost stiffening every blade in the yard. Web's Lawn Service closes the year out on those lawns — a last cut set low, trimming tucked in around the beds, leaves gathered and gone before they mat down and smother the grass. Through the green months it is steady mowing and trimming week after week, the sort of upkeep nobody notices until it stops. A lawn put to bed properly in fall is a lawn that comes back willing in April, and that is the payoff of the whole calendar.
