My friend gave me a set of these card for Christmas and they are pretty cool. Basic stuff but cool non the less. And if your sitting in one place long enough you can always play solitaire, or use the cards to start a fire.
Each card has helpful tips on survival situations
Some are a bit more common sense than others. But good for a newbie.
The website http://www.urbansurvivalguide.com looks pretty slick and they offer 13 different on-line classes covering a wide variety of topics. I have not signed up for any of the courses so I cannot review if any are worth the money. But the cards are small enough to stick in your bag or vehicle and something worth having around to keep yourself or kids occupied in a pinch.
