North of Hamburg the valley opens into flat farm ground along the Papakating, where late-August light lies down long and yellow over the corn. Peters Lawn Service keeps lawns in that country and in the borough itself — cutting, trimming, edging, and the spring and autumn clearing a Sussex County yard needs to look right. Grass on bottomland grows heavy and wants a sharp blade and a patient pace. Nothing about it is complicated; all of it is worth doing properly. An even lawn at the end of a long summer day is its own argument for the trouble.
