Channahon means the meeting of the waters, and you can feel it on the towpath at dawn, mist lifting off the canal where the Du Page slides in. Magic Hands Tree Services, Inc. works the shade of that bottomland — cottonwoods and silver maples that grow fast, throw weight out over a roof, and need a pruning hand to stay honest. Trimming keeps a canopy up off the driveway and out of the eaves; removal handles the ones that have gotten too heavy for their own hinge. Storms track down the river valley all summer, and after a big one the crews are pulling brush out of backyards until the light goes. A cleared lawn, the sawdust raked, the gate latched behind them — that is the whole job.
