There is one good sound in April, and it is an engine catching on the first pull with the whole season still ahead of it. One Pull Lawnmower Shop carries that sound into Southbridge's hillside neighborhoods, mowing yards that tilt toward the valley and trimming the banks a wheel cannot hold. Edges get cut along the walks and drives, beds get raked out in spring, and leaves get gathered in autumn before the slope sends them all into somebody's foundation. Grass runs hard on these hills once May warms up, so the schedule matters more than anything — a week late here shows immediately. A lawn kept on time, straight down the pitch, is the sort of ordinary beauty a street runs on.
