In the fog, on country roads, we used a spotlight & focused it on the grass, at the edge of the road.
Ever get LOST in the fog, on a DARK night???
Years back, here on Freeway 99, we had a 150 Car & Big Rig pile up, in the fog. It was like an ERIE NIGHTMARE!!!! It was SO confusing, it even caused a pile up, in the opposing direction!!!! Tow Trucks were even sent in from neighboring towns!
