Four in the morning in Pana, and the crossing of Route 51 and Route 16 is a smear of streetlight on new snow. BTG Landscaping & Excavation is out in it, pushing driveways and lots back to bare pavement so the first cars of the day find footing instead of guesswork. Come April the same ground turns green and the work turns with it — mowing, trimming and edging the yards of a town laid flat and wide against the prairie. There is a plain satisfaction in a lawn cut in straight passes under that enormous central-Illinois sky. Snow or grass, the aim never changes: a property that looks looked-after.
