I went out, and my car is covered in burnt black crap!! I took one pic, but you can't get anywhere near it, the polic have shut off the A41 completely from the tunnel exit/Argyle St roundabout etc... All the traffic is now diverting down Old Chester Road. Its deffo not Green Lane Scrapyard, as I drove past there. Up neaerer Kerr Channs, so petrol station theory could be correct, or possibly Bathers??
Will grab the single pic I took.
