Minnesotans and the Weather

I've been wondering lately...why is it that we Minnesotans always like to talk about the weather? I notice that pretty much no matter who I'm talking to, the connversation always seems to turn to weather. In our case, it's usually how cold and nasty it is outside. I was on the phone with my parents last night, and they mentioned it had snowed in Duluth where Jena (my sister) goes to school. Snow this early? Yuck!
