Has anyone heard of Dumpster Gardening?

The idea, I suppose, is to transform abandoned trash dumpsters into planters for urban gardening. It seems like a good enough idea for someone like me with a couple empty parking spaces in my lot, but not a single blade of grass. But, are there really a multitude of abandoned dumpsters hanging around in your city?

Let me know if you spot one!
