I just want to put in a quick word...I worked around nukes in the military and had to do extensive training do to that. EMP's should be the least of your worries. If you live in an area that has more than your immediate family in a five mile area, you've got bigger worries. On the other hand if you are fortunate (or unfortunate to city folk) enough to be out in the last bit of uninhabited land than I would think that you've already had problems with electronics and radio signals. Just watch the history channel and you can see that today's weapons are around 100 times more powerful than the bombs we dropped in WWII. That's the TV version. Now imagine this...a country like Pakistan that can't even keep UBL from playing hop scotch on its border has this capability.
