That January of 1977 was a BRUTAL winter. I remember it well.
In Jan the entire Continental US had cloud cover. All states got snow. Blizzard snow hit our area. All roads were closed for several days.
I got Pneumonia.
It was used as proof we were entering THE NEW ICE AGE which was all the rage in the 1970s.
Winter of 76-77.
The Great Lakes froze over..not uncommon but rare.
