South of Walters the country rolls down toward the Red River in mesquite and pasture, and late August heat sits on it like a hand. Morris Farms Meat Company LLC mows lawns and the rough ground where a yard gives way to grazing — cutting, taking the fence corners close, edging the drive, and tidying the line where grass meets gravel. Bermuda thrives in this heat when it is cut on schedule and sulks when it is not. The border between mowed yard and open pasture is a satisfying one to draw. Drawn well, it makes a place look settled against a great deal of open ground.
