By January the middle of Walled Lake is a plain of gray ice, and the neighborhoods ringing it still need a way out to the road. Cam's Landscaping LLC plows those driveways and clears the walks, spreading salt where a north wind has packed the snow hard against a garage door. The rest of the year the same properties get mowing, edging and trimming on a steady schedule, with cleanups in spring to shake the winter out of the beds and again in fall when the oaks finally let go. It is plain outdoor work in a town built around one body of water. What people notice is the result: a tidy lot, a clean line, a driveway that is simply open.
