On a storm night the bridge lights over the Illinois River blur into soft halos and the far bank disappears altogether. Wilson Tree Service & Snow Removal is out under that sky — plowing driveways and lots, opening walkways, laying salt on the ice that forms first near the water. Snow that comes off the river carries moisture, so it packs quickly and takes a firmer push to move. The satisfaction is in the last pass: a drive scraped down clean, the edges squared, nothing left over for a hand shovel. By the time the weather quits, whole streets are ready for the morning.
