From the bluff at Big Hill Park the Rock River valley opens out in long green folds, and that same green runs right down into Beloit's front yards. ADY Tree Landscaping Services keeps those yards mowed, trimmed and edged week after week, so a lawn reads as one clean sheet from the sidewalk to the step. Late afternoon is the good hour for it — the cut lies down in stripes, the clippings come off the walk, and the border along the drive ends up sharp enough to run a finger along. Spring and fall bring the cleanups, when winter's litter and October's oak leaves leave the turf and the beds get their outlines back. It is simple work done attentively, and a well-kept Beloit lawn is its own kind of welcome.
