Dave Mann from Auckland tells how he and his family celebrated Earth Hour '09...
"We celebrated Earth Hour in Auckland at our home by switching on every light in the house, including the christmas fairy lights, and we ran our car engine with the lights on full beam and the indicators going just for good measure.
I had a little drive around the neighbourhood and I noticed several houses doing something similar and I beeped my horn and clapped and we called out to each other and waved.
We had a great Earth Hour celebrating mankind's wonderful achievements in dragging ourselves out of the middle ages and into the age of science and reason."
