The old Packard Proving Grounds still holds its long straightaway off Van Dyke, and anyone who cuts grass for a living understands the appeal of a line that true. Walz Landscaping LLC brings that instinct to Shelby Charter Township yards — mowing in even passes, edging the walks and drives, trimming what the mower cannot reach, clearing the beds in spring and the leaves in fall. Evening is the best light for judging the result, when the sun comes in low and every stripe shows. A yard finished at that hour looks like somebody cared, because somebody did. That is reason enough to do it right the first time.
