I think it was in about 1989 when I-75 was iced over from about Ocala to north of Atlanta. We drove it and stayed on it fine. After some years in MI & MO we new to drive like we didn't have brakes and made safely to our destination in MO for a wedding.Yes, kids were out building small snowmen, and throwing snowballs. Wonderful right? Not so much. Nothing on any Florida highway, or road was geared for accumulated snow, including the drivers. Within an hour, all roads and highways were choked with wrecks, and/or cars that had skidded out of control, and got stuck, etc. It took over 4 hours for them to even make a dent in getting traffic moving. What saved the day was that by then, the snow was melting. It was only the fact that the snow melted, that saved our entire transit system.
THAT was the year my parents decided to move back to Florida. Because of my dad's job, we traveled a lot, and until then all my life we had only lived in tropical places in the winter. I was already suffering bad allergies, and all the winter type ailments (colds, and flu) that I had not been exposed to for all those years. It's like they converged on me all at once. When my mother, and brother woke me up that morning, so I could see the snow, I went to the phone, and booked a flight to Puerto Rico. I had friends there that I could spend the rest of the winter with. I came back in the Spring. By being able to go through the seasons here, and acclimate, by the time winter came, I did fine.
