Riverside begins where the Mianus River gives up its last bend and slides under the railroad bridge into the Sound. J&J LawnCare LLC keeps its yard on Peters Road, close enough that a morning breeze carries a little salt up the street with it. The work is lawn care and landscaping on close-set, tree-shaded lots — grass cut to a clean line, beds held to their shape, a property that reads as cared for from the sidewalk. Come winter the same streets need snow removal instead, drives and walks opened while the streetlights are still on. It is plain, steady tending of the ground people cross every single day.
