By one o'clock in July the Georgia sun sits straight overhead and the ballfields at Roswell Area Park go bright and empty. Cutter Up Lawn Care works right on through it, because zoysia and Bermuda grow hardest in exactly the weeks it is hardest to be outside. Mowing at the height the turf can carry, edging beds and walks, trimming the corners a deck will never reach, then clearing the concrete before the thunderheads stack up over Big Creek. There is a plain, unfussy pride in beating the rain and leaving stripes behind you. The routes cover Roswell and the neighborhoods running out toward Alpharetta and Johns Creek.
