Marshall grew up under a canopy — the avenues around the fountain are roofed with maple and oak that were set out to be exactly that, and every one of them is somebody's responsibility now. Courtney and Hawkins Tree Service takes that on: pruning that keeps an old street tree sound, trimming that lifts a canopy off a porch roof, removal when a hollow trunk has turned into a question of when. The Kalamazoo River runs cool through town, and the low ground near it grows soft, fast wood that breaks. After a storm the cleanup is close work, in tight yards between porches set near the walk. The result is a street that still looks the way it was meant to look.
