First light in LaFayette pools fog along the valley floor, with Lookout Mountain on one side and Pigeon Mountain on the other holding the morning in until the sun climbs high enough to clear it. Josh's Lawn Care starts about the time the dew begins to lift, because grass cut too wet never lies right. The day's rounds are mowing, trimming close to walls and fence posts, edging the concrete back to a hard line, and clearing the walks so the finished yard reads sharp from the curb. By afternoon the valley is bright and the trail of cut lawns behind the truck all looks of a piece. LaFayette and the Walker County towns around it — Rock Spring, Chickamauga, Trion — keep the mowers busy right through the warm months.
