At three in the morning Hartford Avenue is one long empty ribbon under the streetlights, and that is when the work starts. DCJ Landscape Services LLC runs snow removal in Johnston, where the triple-deckers over toward Thornton stack close together and every driveway is a narrow shot between fences. Plowing here is a matter of inches — knowing which apron drains where, which corner hides a hydrant under a drift, where the bank can go without burying a walk. The reward is a whole street of open drives before the first commuter has found their keys. When the sun finally comes up over Atwood Avenue the town simply works, and nobody has to think about why.
