Andrew defends leaf blowers, on the grounds that they offer a tangible benefit along with their noise and pollution.
Our gardener (yes, we have a gardener, don't start with me), Larry, has a rather quiet leaf blower, but it's a blower nonetheless. I'm ambivalent -- those things sure do work -- but I also have a broom.
I also favor letting leaves stay where they fall and/or moving them into my compost bin. Composting is the best thing we can do to both fortify the garden and dispose of organic wastes (both yard and kitchen varieties) with maximum efficiency -- no truck needed to haul it away, all processing done by critters and micro-organisms.
I'm off track and not betting. So goodbye.
