The old canal towpath runs east out of LaSalle flat as a ruler, and the year alongside it splits neatly in two. Warm half: Jake's Lawn & Tree Service mows, trims and edges to schedule, then clears the leaves when the maples let go in October. Cold half: blades down, drives and lots opened, walks shoveled, salt put where the shade holds ice past noon. Snow in this river valley can come heavy and wet one week and dry and blowing the next, and both kinds get moved before people need to be anywhere. Lawn care through the growing season and snow removal through the winter, for LaSalle, Peru and Oglesby.
