There is a line on the map north of here where Georgia becomes Tennessee, and almost nothing on the ground marks it but a change in the road signs. Georgia Line Landscaping works the towns that crowd up against it, mowing, trimming and edging lawns, then shaping the beds and shrubs that give a property its outline. Landscaping is really line-making — where lawn ends and mulch begins, where a hedge stops and sky starts. In this valley the growing season is long and everything wants to blur, so those lines have to be drawn again faithfully. Drawn well, they hold a yard together from the curb all the way back to the rear fence.
