At dawn in August the path around Newton Lake is all mist and birdsong, with a heron standing still enough to be mistaken for a fence post. Grasshopper Lawn Care LLC starts its Collingswood rounds in that early cool, cutting and trimming while the dew is still on and the borough is quiet. Six months later the same streets are under snow off the Atlantic, and the trucks come through with plows and salt to open the drives before the first commuters back out. Both jobs come down to timing — being there before the day starts rather than after it's gotten away from everyone. A clean lawn in summer, a bare driveway in January, and a town that barely has to think about either.
