Bridge Street at four in the morning after a night storm belongs to nobody but the plows. JS Landscaping LLC works that hour, pushing lots down to pavement, cutting a wide lane to every door, and treating the walks before the first shift arrives. Brighton snow can be dry and skittering one week and wet enough to bend a branch the next, and each kind asks for a different pass. The reward is ordinary and complete: somebody pulls in at seven and never has to think about it. That is the whole job, done in the dark, and then done again the next time the sky goes gray over the plains.
