Col, I can remember that in the mid-1950s New Orleans actually got cold enough for snow, and that the snow formed piles on the ground that stayed as such for about 3 days. I was too young to remember issues with traffic, but at the time our subdivision was new enough that we had a gravel road anyway. Paving came later.
I made a snowman and Mom made "snow ice cream" - really just some vanilla flavoring, Pet condensed milk, and a little bit of sugar water poured over a cup of snow. Once every seven years since I was a little tyke, it got cold enough that we would get a brief snow flurry. And, because it is such a rare event, nobody who was born here knows how to drive on a frozen road with ice patches.
But then again, during Hurricane Katrina's aftermath, I had been relocated to Ft. Worth Texas for several months. Even though they DO get more regular snow events, when we had a freezing-weather storm (really hard freeze and some snow / freezing rain on the roads), it made the local news due to the backlog of people waiting for a tow truck to pull them out of ditches and to bring their cars to body shops for repairs. Texans couldn't handle snow either. On the 10 PM news that night, local stations were posting interviews with tow truck drivers who had as many as 10 requests for tow service still pending, and they had already serviced more than a dozen requests earlier. That night, it was GOOD to be a tow-truck owner/operator.
