This is probably not news to most people anymore. But we just starting having our waste collected in new poly bins. Up to now, we have been sorting waste into three streams of wet compostable, dry recyclable, and general waste and having it collected in green, blue and clear bags. But the city is just now getting around to implementing the new waste bins, primarily - from what I understand - to remove the green plastic bags from the wet composting stream.
But never mind all that. My son loves watching anything loud, with moving parts and wheels (and sirens). Just like his Dad.
