Latest Cloud Message?

We just received a strange message from Nick Boole. He claims it came from the black cloud directly to his phone! He faxed us a photo of it from a copyshop. The transmission was poor, but it resolves to this text:

I have a dream: The air is fresh
but smog blows through my heavy mesh
fifteen cars I make them legal
with the fed and for the seagull

Let us know if you can figure out what it means, and post to the sightings. Save the planet!
