North of Horseheads the land narrows into the Catharine Creek valley and runs up toward the foot of Seneca Lake, and winter weather funnels down that corridor with a will of its own. Seneca Hills Concrete and Contracting handles snow along it — plowing driveways and lots, opening walks, spreading salt on the packed spots where the shade never quite lets go. Some storms are a single push at daybreak; others mean going back three times before the sky finally quits. Either way the aim holds steady: pavement a person can cross without thinking about their footing. Serving Horseheads and the surrounding towns each winter.
