Every machine on a Lincoln Park street in January has to start on the first cold morning it's asked to, and R & R Lawn Mower & Snow Blower Repair has spent enough hours with those engines to respect what winter does to them. The snow work follows the same instinct — driveways plowed, walks cleared, salt down where ice sets up hard in the shade behind the house. When a storm comes through overnight, the answer isn't heroics; it's gear that's ready and a route that actually gets run. Snow down here can be wet and heavy one week and dry and drifting the next. Either way the drive gets opened.
