As soon as I finished building the Lego 4206 Recycling Truck I knew what must be done. A Recycle center has to be built so the recycle truck has a place to drop its cargo. The warehouse door colors match the color designated to each type of product to be recycled. Notice the front of the loading dock. I used pieces from Lego's 7045 Hovercraft Hideout to provide a cushion between the truck & the dock. The decals on the signs above the doors are from a Lego 4206 recycling truck set.
