Carbondale grew up along the railroad, and the trains still come through at night, a long horn moving off south toward the river. Threlkeld Lawn Services works the neighborhoods on either side of that line — mowing on schedule, trimming fence rows and alley edges, cutting a clean margin along the walks, sweeping the clippings off before the truck pulls away. Autumn means leaves gathered and hauled, and a final low cut to close the year. Then the weather turns, blades go on the front, and the same trucks plow driveways and lots and open the walks by hand. Whatever the calendar is doing, the property gets handled.
