Round here, the gardeners all set them on blow -and just push the stuff outside someone elses house, or as a huge pile of debris onto the road,(so that at the first drop of rain your car makes no contact with the road surface - beats paying for a white knuckle experience at a theme park)
Thank the Lord I don't live in a cul de sac, I would not be able to open door or see through window due to man -made leaf drifts. : 0 ) So they work, but are not necessarily neighbour friendly!
