Thanks Steve,
I have only just logged in and found your reply.
The fog was really bad down here with visability hovering down to 50-75 feet on Tees Road between Graythorpe Yard and Haverton Hill.
When I got back to Hartlepool from Middlesbrough, the fog was beginning to burn off with some good clear breaks. Had a look at the BBC Tyne camera and was a big foogy but visability good. So drove upto South Shields, got there about 1330 and was greeted with glorious sunny spells and clear sky. Got some very nice pictures and as we were leaving the fog was starting to roll back in.
