On an ordinary Tuesday along the old Atlanta Highway, the loudest thing on a Flowery Branch street is a mower making its turn at the fence. LUV LAWN CARE works those weekday hours, moving property to property with the deck, the trimmer and the blower, leaving each one squarer than it was found. Nothing about it is dramatic — grass grows, somebody cuts it well, the block looks better for it. Cleanups fill the shoulders of the year and mowing carries the middle. Steady work for a town that keeps growing out along this road.
