Air Park sits on what used to be a military airfield on Lincoln's northwest side, and the streets built over those old runways are still wide and straight in a way most neighborhoods aren't, which means TDK Lawn Care, Inc. can run a plow the full length of a block in one clean pass instead of working around tight curves. Open ground still stretches out past the last row of houses here, and wind off it can push snow clear across four lanes of pavement before it finds anything to stop it. Driveways in this part of town tend to be long and flat, laid out for an era of bigger yards, so a single property here can take longer to clear than three closer to downtown. Watching one of those long, straight streets go from drifted white to bare gray asphalt in a single steady run is the closest thing this job has to a straight line. Once the neighborhood's main routes are open, the crew works back through the side streets until every driveway on the list is clear.
