What year was that? I remember in 1989, I was living in Mandarin. I left the house late on (I believe) the day before Christmas Eve and head toward Lake City, my home town to spend Christmas with the family. It was cold AF, I got on I-10 and headed west. I saw state troopers blockade I-10 behind me, deteriorating road conditions, 1-10 was an icy mess. I hit black ice around Macclenny and went into a 360 spin. The only thing that kept from sliding into the ditch was a speed limit sign, I came to rest against it. I drove 40 mph the rest of the way. That night and the next day it snowed pretty good, 4 inches of snow remained on the ground for two days. My (at the time) girl friend was supposed to come the next day, but every bridge in Jax was closed for a couple of days.
That's the last time it's gotten that wicked in north Fla, but we've had flurries now and then.
