I hadn't realized Earth Hour began in Sydney…
I participated last year, and although I consider myself an environmentalist, unplugging everything really made me think about the energy we still use. Some of those appliances have not been plugged back in all year long, and I haven't missed them!
Where have the days gone? 
I stubbed my toe so badly that I thought I had broken it during one Earth Hour! OUr office participates and we will get a reminder on Friday to switch everything we can off before going home on Friday afternoon.
I'm flying out of Sydney Saturday night.Hope I get to see the results from the air.
