Brinks Truck Movement.

This afternoon while traveling in North Jersey I jumped on the Turnpike from downtown Jersey City to Bayonne. When I got on the Turnpike I noticed ahead of me traveling in the left lane an unmarked NJ State Trooper vehicle with lights on. As I got closer I noticed the car was the end car in a convoy with 3 of the largest Brinks trucks I have ever seen. At the front was a regular NJ State Police car then 3 Brinks trucks, a repair van (I guess in case of a flat) and then the unmarked car. They were traveling less then 45 MPH in the fast lane so I am assuming the trucks were carrying gold or some sort of metal. I wonder why this very large shipment was on the move and where it was heading.
I had my camera with me but didn't have time to pull it out as I passed and besides I wouldn't want to have been stopped for taking pictures of a large Brinks shipment.
With all this talk of an impending attack this weekend it wouldn't surprise me if a hardcore gold holder is moving his stock.
