I was the witness.
The jeep was where it is very difficult for any car to get to.
The train was on a siding, near a high traffic highway. The Port of Houston was heavily used in the Gulf War as an embarkation point for heavy equipment.
The jeep was obviously abandoned because it was empty and no one was around it.
There are no crossing anywhere near where it was for miles.
It would be very easy to keep an eye on rail traffic through Houston.
Pro-saddam forces in Houston have been whining on the local pacifica station about how they need to block transportation of military stuff to 'stop the war'.
