They could use other things like sand too. That's what they use in the south. There's no excuse to not do "something" except that I heard they only have 27 snow plows.
As an aside, they are not salting as many roads or plowing as well as they used to in previous years here in metro Detroit either. It's a money thing, not a green thing though. Some roads just aren't getting done and those roads are getting scary dangerous to drive on.
