I'm not sure how much salt it takes to salt up a day's worth of snow. Probably not a ton but a lot. Milwaukee uses more than 50,000 tons of salt every year to keep our roads clear, and we have an army of contracted plow drivers and salt trucks on-hand to handle the streets.
For some reason, I don't think Atlanta, Georgia feels the need to have a fleet of snow plow drivers or salt trucks on hand. They got as much snow in one day as they usually do over the course of an entire winter.
Northerners drive like they've never been behind the wheel of a car in the few hours between when heavy snowfall starts and when the plows and salt trucks get out there and turn everything to salty slush, too.
Let me see if I can explain.
We'll use Birmingham, Ala since I know the facts around that city best.
First, keep in mind that it simply does not snow often in the deep South. Like, it's been 21 years since it snowed in Birmingham. If it does not snow often, people are not use to seeing it, much less driving in it. Their car tires are not designed for it. The state is simply not as prepared for snow as the Northern states are.
Second, the city of Birmingham is bankrupt. It's budget doesn't include an army of plow drivers, salt trucks and mounds upon mounds of brine/salt/sand. Normally this would not be an issue, since as I stated above, it hasn't snowed in 21
Third, the people in Birmingham, Ala were actually told they would get just a dusting instead of what they got. They, yet again, were unprepared for not only getting snow but for getting the amount they got.
The result of those three things? A royal mess. People died. Parents couldn't get to their kids, kids were stuck in school overnight, adults couldn't get home from work, people were stuck on the roads unable to move.
It's not funny. It's rather irritating to see people laughing at the South about this, especially when you didn't see the South laughing at the North when, two years in a row, they got smacked with hurricanes.
