Down in the Stockade the streets bend toward the Mohawk, and the brick fronts hold the afternoon warmth long after the river has gone silver. Mohawk valley lawn care mows and trims through the city's small deep yards and the wider ones out toward the flats, keeping every edge square to the walk. A city lawn is a matter of inches, and getting the line right along a hundred-year-old curb is its own kind of pleasure. Beds are mulched once the tulips are done, and leaves are gathered in the weeks when the maples in Central Park let go all at once. Work runs across Schenectady into Rotterdam, Niskayuna, Scotia and Glenville.
