The Riverside blocks run tight. Two-family houses, driveways barely wider than a car, front yards you could cross in four steps. The Yard Bros mow, edge and trim those yards all summer long, Saturday afternoons especially, when the whole street is out and every finished lawn is on display by dinner. Leaf season brings the rakes and blowers, clearing the curb strips and the corners behind the steps where everything collects. Small lots reward precision more than horsepower, and a clean line where grass meets pavement is the point of the whole trip.
