Caseyville's older streets run in a tidy grid of front yards and sidewalks, the kind of blocks where a well-kept lawn gets noticed and a neglected one does too. Js Lawn Service LLC works those blocks all through the mowing season, cutting, trimming close around posts and mailboxes, and clearing the clippings so the walk stays clean. In October the job becomes leaves; by December it becomes snow, with driveways opened and paths cleared so the mail gets through and the steps are safe underfoot. The town itself does not change much from one end of the year to the other, but the yards do, and keeping up with that turn is the craft. Every season has its own order, and this one follows it.
