I've always told my Southern relatives that one becomes a real Minnesotan the first time s/he goes out with an unzipped coat in 20 degree weather following a week or so of sub-zero temps. Today was the first day in the 20s after a two-week cold snap, and lots of people were out without their big coats. I also saw some fool driving a convertable with the top down! In 23-degree weather!! DAMN!!!
