Autumn in California
Of course, since this is California, when the leaves fall, the city takes care of cleaning them up. An army of men with leaf blowers are scouring the streets and roads and parks, blowing all the leaves off of the pavement, and onto the grass, or into big piles, to be picked up later by huge trucks with gigantic vacuum cleaners on the back of them, that suck up all the leaves. The leaf blowers are amazingly loud -- my cat went and hid under the bed when they were working on my street a few days ago -- since they are gas powered engines strapped to people's backs. But they do the trick much more effectively than a broom or water or anything else. Leaves respond to the wind, as they are meant to do, not caring if it is artificial or real wind blowing them around.
So although the leaves come and go, what one is reminded of here in California is that the trees, and the roads, are eternal.
