At Riverview Beach Park the Delaware widens toward the bay, and in April the wind off it is still cool enough to make the new grass wait a week before it commits. ARTIZTIC CREATIONS works the lawns of Pennsville Township once it does — mowing, edging along the walks, trimming the corners tight, and clearing away what winter left in the beds and along the fences. Down here the river light is broad and low, and it flatters a lawn that has just been cut. There is craft in a border you could draw a line by, and it costs nothing but attention. Spring in Salem County is worth waiting for, and worth meeting ready.
