I've driven through snow quite a bit, esp. in Pennsyvania, Delaware, Maryland areas. Drove a few hundred miles in snow so heavy I couldn't see 50 yards..
What we had in my area, (LaGrange), and I assume the Atlanta area as well was not snow. It was mixed rain and sleet, followed by about an inch or more of ice pellets.
The warm asphalt began to melt them, but the temps were so low they immediately froze back into about an inch of glare ice. Then a little snow fell to cap it off.
Unless you've got studded tires, you can't drive on ice. I managed to get around to work, but I have a heavy rear wheel drive van with about 2500# of tools and equipment.
A two wheel drive pick up was about as useless as can be, and a front wheel drive or 4 wheel drive in the hands of someone who has never driven on such is just danger on 4 wheels.
We have no salt shakers, no sand trucks, now plows to speak of.
Was it a lot of craziness? Yep, made worse by the fact that everyone hit the road at once....
Will it happen again? Probably.
