Thanks again for all of your help. If I may follow up with one more question?
The tractor trailer will be crossing the border and will be "x- rayed" by a machine
where you drive the whole unit into a garage like structure. I have questioned the border officials and they claim that since 9 / 11, they do this with every tractor trailer unit, and that it is not really x - rays, but some type of gamma ray. Again, they insist that there will be no ill effect to the magnetic tapes. Any ideas on this? I am not sure they are easily talked out of not x raying the trailer, even if I accompany it.
