Here is the before picture of a small lawn. You can see the leaves are almost the height of the first step then as they gp around the house they are about 10 to 12" deep. Most of these leaves come from across the street and from the house next door. You can see the pine tree on the left and in the back where a neighbour has put up a fence to stop the leaves. There is a decent sized maple tree jut to the right out of the picture. The back lawn is even worse for the amount of leaves.
