First, I would like to thank those who offer this site as a teaching aid and means of gaining real information with "non-panic" mannerisms. I have found the product reviews most helpful.
I have three grown children with their own families (and my Grandchildren) living in US cities where they may be at risk of natural or manmade disasters. I am concerned for their abilities to deal with the public reaction (chaos) to "an event" and am preparing survival packs for them. This kit will be unlike (but similar) to a survival kit used when you find yourself in the wilderness. My question: are there any sites that discuss urban survival in urban chaos??

I thank you in advance for any information.
Dale
