Nah.. not entirley true mate, I know for a fact there was a 10 mile exclusion zone at Immingham, they had cops on all the roads leading there turning all lorries away unless they had proof they where delivering in the area, a mate of mine got turned away, he went back later in his car, and they had troops there with Bulldozers just incase anyone made it.
Funny how that has been 'left' out of the news!!
