Morning in Port Washington starts with light coming off Manhasset Bay and the first train pulling out, and the lawns from Baxter Estates out toward Sands Point are still holding dew. JGB Landscaping LLC is into that early hour, mowing, trimming and keeping properties tidy along the shaded old streets and the open ones near the water. Grass on this peninsula grows thick where the trees allow it and thin where the salt reaches, so the cut changes block by block. What does not change is the finish — even passes, tight edges, everything cleared away. By afternoon the yards look as calm as the bay does.
