But it's “settled science,” doncha know.
And what a blizzard it was. Lots of people died. I lived in Chicago at the time, my dad passed away in Florida, started out driving just as the storm began, drove to Nashville but I-24 was shut down, tried I-65 to Birmingham but State police had it blocked, drove SW to Memphis, down the Mississippi, along the Gulf, looking at the snowmen in front yards in the Florida panhandle, and finally, after 36 nonstop hours (except for pee and gas breaks) made it to Orlando just in time for the funeral. My daughter on a school trip to DC was stuck in Pennsylvania for 3 days.
So "22 years" likely a very-cherry picked date.
