This gives me an idea for a new business type, where you do nothing but rake leaves and sell the compost. Of course, you'd need a sub-hood where it's always autumn, and that feels a bit cheaty.
You rake leaves? No, you set a minimum neatness level on your visitor controller, and then your townies rake leaves for you. You might want to combine this with a Bandatron; that way your townies pay to rake your leaves, and then pay again for the compost. Remember, in Soviet Russia, leaves rake YOU!
