I'm in Wisconsin, and I just got the bike with spiked tires out today. Even if there's not a lot of snow, I prefer to sacrifice one bike to road salt than have to maintain my "nice" bike through the winter.

People act like I'm some kind of freak when I arrive at work on my bike in the middle of the winter. But I remind them that there are people who work all day outdoors in places like Alaska and Canada, and 20 minutes on a bike doesn't even come close.
