Tying to treading lightly

I did the survey at www.myfootprint.org the other day and although I did better than the average person in my part of the world I am still walking way to heavy on this gift from God that we call earth. So, after a couple of times hiring a petrol mower I've decided it's time to get a push mover, and my little flymo is a thing of great beauty, all the very best of sweedish design.
