The key phrase that a father must say in this scenario is: "Don't tell your mother about this."
Jarrad Provost of Fredericksburg, Virginia attached a leaf blower to his son Roman's Power Wheels battery-powered toy car. This means that the tyke is ready to take on the chore of clearing off fallen leaves--a task normally given to an older child.
The car may not have enough power to move over rough terrain, so I suggest setting Roman up on an ATV for other areas. Then hire him out to the neighbors. Cut Roman in for a percentage, and Provost has a profitable business in the making.
