The old rail line through Northfield is a bike path now, running straight across town under the pitch pines, and in late summer the whole stretch hums with heat and cicadas. Brady's Landscaping keeps lawns on either side of it holding their green through that spell, when sandy shore soil dries fast and grass needs a steady hand. The work is weekly and unglamorous — mow, trim, edge, blow the clippings off the concrete — and the payoff shows up every week in a yard that looks looked-after. Fall brings the leaves down in a slow drift and the mower gives way to cleanup. It is a small pleasure, turning a shaggy corner lot back into something square and deliberate.
