What a lot of know-alls on here don't seem to consider is what happens when the staff can't get to work? You can't just go and drag people off the streets; they need to be trained. If the people can't get there it doesn't matter how many snow ploughs and other gear you've got. What's the answer? Train lots of people and have them sitting around for 20 years doing nothing until it snows again? The difference between the Scandinavian Airports and us is that they have snow almost every day whereas we don't.
