A wet May in Sussex will put anybody three days behind, and the grass has no interest in the excuse. Sussex Yard Services Inc. reads the sky and takes the openings — cutting between showers, working the drier ground first and coming back for the soft spots once they firm up. Mowing, string trimming and edging make up the routine, with the spring and fall cleanups handling everything the weather leaves behind. Borough backyards here run small and irregular, full of steps, sheds, clotheslines and old plantings that have to be worked around rather than through. Getting all of that done between one storm and the next is its own small craft, and the finished yard shows it.
