After a heavy fall, the bare cottonwoods around Centennial Center Park hold snow in every fork until the wind lets it go in slow white sheets. Eden Tree Care spends those mornings on the ground beneath them, plowing driveways, shoveling walks and paths, opening entryways and treating the ice that forms where meltwater runs off a roofline. Storms here often come in warm and wet and then freeze hard overnight, and that second act is the one that puts people on their backs. The work is simple and exacting: down to the surface, wide enough for two, edges squared. There is a plain pleasure in seeing a whole property open while the branches above are still loaded.
