First, they are "plowing and blowing", not shoveling (or not shoveling much) - if you have a significant amount of snow, shoveling is just impractical as well as back-breaking. Second, even if you don't get snow overnight, you get the drifting they mention, which is where winds blow snow onto the nice clean driveway you had cleared previously. Drifting can be quite significant with lots of snow and big open areas!

Lastly, not the OP, but winter is my favorite season for the most part, and I love being around lots of snow!
