I currently live in Pennsylvania (near Allentown), and used to live in Atlanta. I've driven in snow in both states, and snow is definitively worse in Georgia.
Sure PA gets more snow than GA will. Before any snowstorm you will see salt spreaders on the road dusting the road, and huge snowplows can be seen idling in the median of the interstates waiting for the snowfall. PA gets snow every year so PA does have the resources. Drivers in PA know how to drive in snow. I don't know how people in Wisconsin do it, but in PA it is not 10 miles under the speed limit. I've been on the interstate (speed limit 65 mph), 2 lanes, but almost everyone is in 1 lane, and traffic moved at a steady 20-25 mph. (I 81N today, between Frackville and Hazleton). Cars stayed in the tracks of the car in front, and left plenty of room between cars. Driving slow and careful and taking longer is better than driving fast, skidding out, and not getting there.
When I lived in Georgia it rarely snowed. I grew up in Cordele (watermelon capital of the world). I remember only about 2 "snows" in about 15 years, each less than 2 inches. Georgia naturally does not have the snow moving equipment that the northern states do, quite logical, not really needed most of the time. The roads are not designed as well for snow (ex, the I 75N / I 85N merge in Atlanta, with the merge lane in the middle. People on 85 trying to go right for the exit ramps, people on the right trying to go left to avoid the fast lane exits) A lot of people in GA have lived in states that get lots of snow, so GA drivers do know how to drive. Tire stores in GA do sell snow / traction / anti-skid tires. It is just that they don't have enough recent practice with snow driving.
I've heard the joke that in northern states that snowfall of 6 inches or so doesn't make the news and it is business as usual, while southern states will close school with a 1/4 inch of snow on the ground (yes, that happened once in GA). But without the salt, grit, roads with lots of bends, and lack of practice I wouldn't want to drive in snow in GA.
(As a side note, Georgia roads have the definite advantage of not having a many potholes as Pennsylvania has, the pothole capital of the world)
