Some folks declaring a 'no electricity' one evening a week for games and only have a lantern with out TV they can visit and re-connect, reading might be a bit more of a challenge with less light. Getting out a simple card game might be fun. You might even find that the kiddos go to bed earlier and you all might be more relaxed.
Maybe you can consider a walk in the moon light, or to a farmers market. Put up the kids play tent in the living room or back yard to enjoy the last of the summer weather. Gather what you need ahead of time for a more successful adventure!
There was a powerful thunder and lightening storm with a good soaking rain that went through here Sat. night so having things on hand in case the power goes out is a great idea and why not prepare ahead and plan in some fun with it?
