The weather that shapes Mercer comes down out of the northwest, off Lake Superior and over the Michigan line, and it can drop a foot on the Northwoods while the sky still looks undecided. Rockstar Tree Service LLC works with that: mowing, trimming and hauling out yard debris through the green months, then plowing drives and opening walkways once the storms begin stacking up. Yards up here are cut out of white pine and hemlock, which means shade, needles, and borders that want attention to stay sharp. In winter it means drifts piling exactly where the trees funnel them, and knowing those spots is half of plowing well. The reward either way is the same — a place that looks kept, and a driveway you can actually get out of.
