At five in the morning in May the woodlots along the river corridor are so loud with birds you can hear them over a running truck. Nature's Outdoor Solutions starts its days in that hour around Owosso — mowing the open ground, trimming carefully in along the tree line and the beds, clearing away what the wind and the season leave behind. Yards that back onto woods take a lighter touch and more patience than an open lot, and that is a good part of the work here. When the cold settles in, those same properties need their drives and walks opened, and the trucks go out with plows instead of mowers. Different sound, same early start.
