Your assignment this week is to include a portable radio in your 72-hour kits.
You can go as cheap or as expensive as you'd like, but keep in mind size and weight. There are battery-powered options and also hand-crank options. It could even be something as simple as a really old "Walkman" type radio with earphones.
Here's one that my sister gave to us for Christmas last year:
It is a hand-crank flashlight/radio combo. It is incredibly light and made of plastic. It uses 3 LED bulbs. It only does one band of radio (FM) though, and there is no dial - it just scans through any available stations.
I did see some similar options like this available at Walmart last week back with the flashlights in the Sporting Goods area. I didn't look very closely at the prices though.
If there is more than one adult in your family, you may want to keep a radio in each adult's kit. Or if you have older children, you could include one in their kits as well, for them to listen to for entertainment/distraction/passing the time/etc.
