My neighbor: has a gardening service mow their lawn, driving from who knows where in a pick-up and a big van, using gas-powered mowers and a gas-powered blower.
Me: Do it myself, with an electric mower, and pair of hand-operated grass clippers, and a rake and broom.
My way is not only less carbon intensive, but is also better exercise… and much quieter and less annoying.
[Update: I’m being punished for my smugness with blisters on my hands.]
