The one thing on this earth that I wish was never invented is the leaf blower. So damn annoying. Use a rake!
I'm sure lots of people with leaf blowers wouldn't mind if you spent several days or even weeks raking leaves. They don't have that kind of time, which is why leaf blowers sell so well.
Really, they were not invented solely to annoy people. They were invented to save people using them time and effort. Get some earplugs.
