The Cass River loops through Bridgeport slow and brown, and past it the valley opens into beet fields flat enough to watch weather coming for an hour. Allen Benjamin Tree Care Inc. works those farm windbreaks and the township yards on both banks. Tree removal when a cottonwood by the barn has started dropping pieces of itself, tree trimming along drives and fence lines, pruning that gives a young shade tree one strong leader instead of three arguing ones. Storm damage cleanup out here gets measured in acres of brush and one clear lane back to the road, finished before the ground softens. There is a plain pleasure in a windbreak that looks intentional again.
