I recall trying to drive to work in New Orleans on a very rare snow day in 1982. My car wasn't working well in such low temperatures and I wasn't at all happy driving on the roads. I turned around after three miles and went home. My boss was really mad at me. It worried me at the time but now as an older adult I would tell him off without a second thought. My life and my car are worth more than a days pay.
There is no snow removal or road sanding there. I do recall the city rigging some regular dump trucks to drop sand in some parts of town. They used workers with shovels to spread the sand. It wasn't very efficient.
