On a Mercer County side street the Saturday sound is a mower two houses down, a screen door, and somebody's dog objecting to both. M&R Lawncare Management is often that mower — cutting, trimming along fences and foundations, running the edge of the sidewalk, clearing the drive before pulling out. Small-town lots reward attention; the difference between a yard that is cut and a yard that is finished is about ten minutes of trim work. Those ten minutes get taken. Block by block, that is how a town keeps looking like itself all summer.
