West of Dawsonville the mountain lets a creek go and Amicalola Falls comes down the rock in stages, loud all spring. April in these foothills is dogwood and green haze and a great deal of grass waking up at once. ALF Lawn and Pest Solutions meets it with a steady mowing schedule, edged drives, trimmed borders and walks blown clear. On this ground a mower has to follow the slope instead of fighting it, and a cut that lies right on a hillside takes some doing. Done well, the yard looks like it belongs to the mountain standing behind it.
