It must be spring -- the landscapers are out. This morning, there was a guy scraping up leaves along the fence at the bus depot with a snow shovel, and at the hospital they were out with leaf blowers. Also, they had a gizmo I've never seen before -- I can only call it an power broom. Built like a gas-powered weed whacker, but with a big horizontal spinning brush at the business end.
Actually, I also saw the riding-mower version of this implement last winter, buzzing slush off the sidewalks around the Galleria.
