This post comes early or late, depending on your geographic position, but we've still got a few minutes yet till 8:30 local time, so it's not technically late from my point of view. I was thinking of things to do during Earth Hour:
*Trivial Pursuit, anyone? Play board games.
*A stroll through the neighborhood at night can be fun.
*Munch on food prepared without electricity.
*Try to read by candlelight and be thankful for electricity.
*Your electronic toys are all effectively broken for an hour and reading isn't much of an option. After you've played a game or two, what could you and your significant other possibly do to pass the time in your dark, romantically candlelit dwelling? Hmm...
