I probably always take a picture of these city workers who vacuum the streets every fall to pick up the leaves that drop from our huge number of trees. Residents have to sweep all leaves on sidewalks and yards into the tree boxes located on the sidewalks, which are then blown by guys on foot into the street, to be swooped up by the truck and its giant hose. I find the whole idea of vacuuming the streets just fascinating!
