By the middle of July, Lake Decatur takes the heat off the afternoon a little, and the yards along the shore run down toward the water in long soft slopes. T & T Lawn Care mows, trims and edges through that stretch of summer, when the grass grows faster than anyone wants and the air off the lake near Nelson Park stays heavy until dusk. Slopes and shorelines take a steadier hand than flat ground, and the crew works them accordingly. What people notice afterward is the quiet order of it — the turf level, the borders clean, the walks clear enough to go barefoot. Then it is another week, and back around again.
