Jayne's Hill rises just west of town, the highest ground anywhere on Long Island, and from up there Huntington Station is a green roof of oak with lawns cut into it like clearings. Looks Great Services Inc works down among those clearings — mowing, trimming, edging, spring and fall cleanups on street after street of them. May is the month that tests everybody, when the grass grows an inch overnight and every yard wants cutting at once. Keeping ahead of it is a matter of showing up on the same day, week after week, whatever the sky is doing. Stand back afterward and a lawn has a kind of order to it that you can see from the corner.
