Up at my trailer I blow the leaves into the woods. I don't pick up anything. At home, I blow them out away from the fence line and the landscaping, then mulch.
My son-in-law has a good acre and a half of woods around the home. It would unthinkable to rake that many leaves. Makes much more sense to blow into a tarp, or up the loading ramp on a trailer, and haul them away.
If you don't have a yard, or don't have a yard you care about, or it is the size of a postage stamp then the leaf blower doesn't make sense.
Just saw Rek's post, makes more sense
