I am located in Chicago ‘burbs as well, and back in the mid 80’s, I managed to get a week long pass from the Army. Came back home, and a snow storm hit us. We got about 6 inches of snow, everything was fine, until the snow hit Georgia... I was told to return ASAP because of the massive snow storm that hit Fort Benning... So, my grandfather drove me down back to the base. We endured several inches of snow on the highway all through Illinois. When I awoke in GA, the roads were mostly closed, the National Guard was out helping motorists, it was so bad. They had..... about two inches of snow.... lol.
Cars were in ditches, abandoned, etc. Grandpa went to the trunk, got the tire chains and dropped me off at base, then returned home. The entire state was basically a disaster. The only vehicles moving around were trucks. The big rigs were just rolling through, but back then, there were no snowbirds so to speak, folks from GA had lived there for generations and snow was something from Mars I guess.
I also remember reading back then, that that snowstorm that hit the south was proof of the coming ice age..... We were pretty much all doomed by the year 2010.
No matter how things change... they always stay the same.
Saying it will be worse than the 1967 one.
