On a summer evening the Riverwalk boards along the Fox fill with people walking nowhere in particular, and behind every street off it are lawns that got cut that week. E.F.P. Express Landscaping Service cuts a good share of them — mowing on a steady rotation, trimming close, edging clean, hauling the spring and fall debris away. The winter version of that same route is a plow blade: driveways opened, walks shoveled, salt spread where the sun never quite reaches. Speed matters in both seasons, but so does the finish, and the crew would rather make one more pass than leave a ragged corner. Serving McHenry along with Lakemoor, Holiday Hills and Island Lake.
