I legitimately didn't know that it does snow every winter over in the US, since so many americans have told me that they have never seen snow before in their lives.
Well, Devi, the thing about the US is that we are the only country in the world to reach from well above the arctic circle to within the tropic zone. We are also the only country to have literally every terrain and biome type on earth (except for one).
Add to that the fact that we are the third most populous country in the world AND the third largest, millions of people are going to live in areas that only rarely get snow.
By the numbers, though, 60-85% of the US (by land area) gets snow every winter.
((Then again, I don't understand how some people don't travel. I mean, we have the most complex highway/roadway system in the world...travel is super easy. My dad's job kept him moving, so I have spent time in literally ALL of the states at some point in my life (always by car...except Hawaii... :P). We even camped all the way down from Alaska when we moved from there down to Virginia (a 5k+ mile trip). Now that I'm used to riding in the car, when I want to go somewhere I'll just hop in and go driving. If any U.S. citizen just made a long weekend road-trip, they could get to some place that has snow in the winter regularly.))
