Saturday morning downtown, before the doors open along Chicago Street, the walks in front of the old brick fronts and the Tibbits Opera House still hold the night's cool. Boots & City Lawn Care Services keeps the green parts of that picture in shape — the setbacks, strips and small side lawns a business district lives with, mowed and trimmed and edged so the storefronts read clean from the curb. The route runs outward from there too, into the yards a block or two off the main run. Spring cleanup clears the grit and winter litter; the fall round takes the leaves before they pack down. A town that looks tended is a town people slow down in.
