On winter evenings the light from the shops on Putnam Street falls out across the snow in long yellow rectangles. Go Green Landscapes LLC is usually working past that hour, plowing driveways and clearing walks so the morning starts easy for somebody else. The rest of the year those same properties get mowed, trimmed and edged, with a cleanup when spring breaks and another once the leaves are down. Mid-Michigan does not do gentle transitions — the last mow and the first plow can sit three weeks apart — so the changeover happens fast. Williamston, Webberville, Okemos and the roads between them are all on the list.
