First light comes up over the Chattahoochee and the fall-line rapids are still throwing mist when the mowers come off the trailer. A-1 Lawn Care works the yards of Columbus, Georgia, cutting the grass down to one even sweep and then edging the walks until the line reads clean from the street. Mowing, trimming and blow-down fill the morning, and the difference shows before the day turns hot. By the time the river town is fully awake, a whole block stands squared away. That crisp border along a Columbus driveway is worth getting up early for.
