1974t150v Agree about the cages, The one I have everything that goes in it will be in a box then wrapped with aluminum foil. This way is it goes though the cage there is another small cage.
We will not know how strong an EMP because there are many ways for an EMP to happen. If they really know what they are doing then they can take down the Country, but they may try and it may end as a not so strong EMP. It has never been done. Some Cities may get hit hard and other cities may get a smaller EMP. Some of the metal of the vehicles may do what a cage does, we just do not know. So I also agree with Jeff.
