At four in the morning the lots along the Route 202 circle are blank and blue, and the only sound in Flemington is a plow blade finding pavement. CSR Commercial Snow Removal LLC works that hour on purpose — storefront aprons, office drives and truck yards cleared and salted while Hunterdon County is still asleep. There is a real satisfaction in a lot that opens on time: curbs visible again, stripes reappearing, the drift by the loading dock hauled off instead of shoved aside. Winter arrives down the Raritan Valley in a hurry here, and the whole task is staying a step ahead of it, storm after storm. By the time the first shift turns in off Route 31, the pavement looks like nothing ever happened.
