is it like those crushed ice drinks you have in summer? or is it like lots and lots of really small bits of hail? or is it just like cold sand? how do you get around when its snowing? do your windscreen wipers stick to the glass? are you allowed to drive when its snowing? how do you see where you are going? do they really have big trucks that drive around and scrape the snow off the road? is it true that you have to drive with chains on your wheels?
