One Second after was a pretty awesome book. Mythbusters did a show on EMP once. They went to some governmant facility where they create and EMP and pass things through it to test for hardening. On mythbusters they drove a car through it and the car came to a stop. The computer fried and that was it.
Anyway, great book, and well thought out. Especially the fact that they hit in the early spring, before the crops were in the ground. One wonders how the fuel delivery and agricultural systems would do in a situation such as this. Hoefully, better than they did in the book.
Ok, I'm going down to the basement now to count my food and medicine stores. lol.
