Grass takes a line the way water takes a channel — mow the same direction long enough and the whole lawn leans that way in the light. Turf Line Services works with that in Williamstown Township, laying stripes that read clean from the road and holding the edges square along walks, drives and beds. The routine is mowing, trimming, edging and the seasonal cleanups that make the first and last cuts of the year possible. Properties out here run big, part yard and part field, so the pattern matters more than it does most places. On a still July evening those lines hold until dark.
