Commercial landscaper here... Companies/people using leaf blowers are wasting everyone's time and money. Period. Blowing around leaves that you can easily rake up is simply an idiotic, colossal waste of energy, and quite frankly a pain in the (r)ear, and as multiple posters pointed out, disturbs your thought process with the loudness. The crew using leaf blowers instead of rakes or brooms is quite ridiculous! Every time I see a crew blowing around leaves instead of taking the time to rake them up, it simply makes me laugh! Fools.
