I wish I had mod points today.
This is a 5-worthy informative response.
It takes me three or four full afternoons on my riding mower to mange all the leaves that fall on my decent-sized suburban yard. I'm fenced in, so the leaves aren't really going anywhere (and where do people think they go to? The ocean? A lake?). I let them sit one year and it killed much of my grass.
As for blowers, I have an electric, and for moving things around in the fall, I have to use it at the beginning of my session, then recharge it while I work elsewhere, then I can blow some more at the end. I do wish I could blow all the leaves I wanted when I wanted.
