By late afternoon the brick along Main Street gives back everything it took from the sun, and the shade under the Upper Common maples becomes the best real estate in the city. Breau Lawn & Landscape Co is still working at that hour, mowing the last stretch while the light goes gold along the hill. Fitchburg lawns tend to be small and steep and full of corners, so every one of them gets hand trimming where a mower simply cannot reach. Edges crisp, clippings off the sidewalk, gate latched behind them. Small things, but carried all the way to the end.
