Good point about that, MJC - too many people here blow leaves or grass into the street and hope it'll just go somewhere else. Usually into drains or into the creek.

If the leaves are mulched in place on the ground, or if they're piled on the driveway and mowed over they reduce in volume by about 90% and then can be put in beds, spread on bare spots, or put in the compost. I end up with a lot of other people's leaves piled along the curb so I use a big plastic dustpan thing to scoop from the street and plop onto the turf, then mow them there. I dislike blowers for many reasons so will never use one here. (And I don't scoop those leaves often enough for them to be light, usually they've already started composting there in the street, so they don't blow easily.)
