Saturday mornings in Pleasantville and the streets around it have a particular sound in summer, and a good share of it is mowers working through the neighborhood grid. Martino Lawn Care INC is part of that weekly music in Mount Pleasant — cutting, trimming, sweeping the walks, moving on before the day gets hot. The lawns here are modest and close together, which means the edges show; a straight border along the sidewalk is the difference between mown and cared for. When winter comes the same streets need the other service, driveways opened and paths shoveled before anyone has to go anywhere. Fall cleanups sit between the two, clearing the leaves out so the grass goes under the snow in good shape.
