No fog, no ice here - north / east Yorks border, despite it being predicted. Pea Soupers were what we got in the 1950/60's, a yellow fog which you could almost chew it was so thick and traffic would be almost at a standstill because no one could see where they were going. The police would be out at junctions, with paraffin burners, trying to lift the fog enough at a junction so drivers could see them. I remember one junction in the early 60's, where 4 PC were needed, leading drivers safely across a junction. Bus conductors would be out walking in front of buses, with a torch, leading the way for the driver. Drivers would fit yellow fog lights in their attempts to perce through the thick fog.
All a result of the massive amounts of coal being burned by industry and inefficient home fires.
