Florence sits up on the old river bluffs where the streets bend with the land and the yards come in every shape but rectangular. Calvin's Mowing and Lawncare knows those lots — the narrow side strips, the terraces that drop toward the alley, the corners where a big deck simply will not fit — and cuts them by hand-guided pass until the whole thing reads even. June evenings up here smell like cut grass and river damp, and the sound of a trimmer working a retaining wall is about as close as the neighborhood gets to a summer song. Edges get their own attention: a walk with a true line makes a modest yard look twice as cared for. Week after week the route comes back around, and the grass never gets the chance to look neglected.
