At dusk on a long block running west toward the Burton line, the day's last mower shuts off and the street settles into that particular summer quiet. Whitney Lawn Service LLC works blocks like that one across Davison — mowing on a steady cycle, trimming the corners, edging so each yard finishes with a clean line at the concrete. Half the year that is the whole job; the other half it is a plow blade and a driveway that has to be open before anybody leaves for work. Between the two there is a single satisfaction: a property that never looks neglected, no matter which season is doing the talking. Genesee County gives you plenty of weather, and the work is meeting all of it.
