In case you've been in the dark, you will be for sure come tomorrow (March 28th) at 8:30pm local time. That's when major corporations, including those in the travel industry, are turning off their lights for Earth Hour and to shine a spotlight on climate change. Abercrombie & Kent and Fairmont Hotels & Resorts are two key participators (their PR person was the first to alert me). So far 2,140 cities, towns and municipalities in 82 countries have already committed to VOTE EARTH as part of the world's first global election between Earth and global warming. So if you're traveling or flying and all of sudden, all the lights go out for an hour (the Eiffel Tower, Golden Gate Bridge and Sydney's Opera House are a few of the participating landmarks around the world) - don't be alarmed. It's just Earth Hour.
