Getting schools days off due to weather can depend on a lot of factors. How often it snows and types of snow; type of roads; hilly, flat, gravel or blacktop roads; thier condtions-how often salted, town or country settings, and other factors. Cousins in Canada laugh at the kids getting school off here for snow when to them it is nothing and we say it is cold when to them is it nice weather. But let them visit here in the summer and they are dying from the heat and humidity that we don't even notice. I think the programers tried to find a middle ground, and that would be hard to do even then with players from so many different countries.
I haven't played winter yet, so I am waiting to see how close it is to what we have here in my home area, Ohio (borders on KY and WV, so we have lots and lots of hills here).
