Co-operation will be necessary. In "One Second After", skills such as electrical, phone service, steam engineering, food preservation in the absences of refrigeration, homopathic training, making of clothes and such and most importantly leadership skills and ability to make good decisions quickly with critical thinking skills. Military training and an understanding of human nature and willingness to accept what ones sees rather than rationalizing the obvious......Key.

I encourage all to read this book...you will not be disappointed.
