Mill Creek winds past Avoca under the old rail trestle, and the trail beside it is about the only thing in this corner of St. Clair County that is not a straight line. The rest is Thumb farmland, level and open and hard-working, and the lawns here sit in the middle of it with room to breathe. Forever Green Lawn Service mows and trims those yards through summers that come in hot and green and end in clear, cool September afternoons. Edges along the drives get cut sharp, clippings come off the walks, and the yard looks finished rather than merely cut. Leaf work in fall and a clearing pass in spring handle what the open wind piles into every corner.
