In Bay State Village the Mill River runs low and green under the footbridges, and the yards that step down toward it hold their grass late into the fall. 360 Cleanup works those lots the way the river works its banks — steady, patient, leaving the edges clean. The rounds are mowing, string trimming, a crisp cut line along walks and drives, beds cleared of what the maples let go, and the whole yard raked out to the last corner. Spring work starts once the road grit washes off the pavement; the closing cleanup ends when the light goes copper over the western hills. What comes back is a lawn you want to stand in the middle of.
