Minnesotans develop the "winter hunch" which is actually two different things with the same name. The first winter hunch is when people are walking outside during winter. Good posture disappears in Minnesota at this time and is replaced with hunched shoulders and a bowed head. This is partly because people are trying to shield themselves from the cold and partly because their winter jackets are so heavy that they can't stand up straight anymore.
The second winter hunch is one that most Minnesotans think they have. It goes something like this, "Uff-da, I got a hunch it's gonna snow tonight, and ya betcha we're gonna get stuck at home tomorrow." "Yup, better head to the grocery store and buy us some more lefse/flour to make lefse to get us through."
Two lane roads turn into one lane roads overnight. When the snowplow goes through, it pushes all the snow from the middle of the street onto the side of the street, creating huge mountains of snow right along where cars would normally park. This leaves little to no room for parking and definitely space for only one car to drive on the street at a time. If you're heading up a hill in winter, you better pray you don't meet someone coming down because one of you is going to have to back up, and it'll probably be you because the other guy won't be able to back UP the icy hill to let you through.
Small children disappear during the winter and are replaced by small abominable snowman-type creatures. Some theorize that this is due to the 14 layers most parents put on their child before allowing them to go outdoors in the winter.
Ya sure, ya betcha it's cold! 'Nuff said.
People who visit Minnesota in the spring bring home tales of ghosts and strange people who wear shorts when it's 48 degrees outside. A typical Minnesotan's skin only sees sunlight for about 4 months out of the year which means that after a long winter, they're literally as white as a ghost. Minnesotans are also known for thinking that any temperature over the freezing point is shorts and sandals weather.
Winter in Minnesota would be the perfect time to commit a crime. Everyone's bundled up from head to toe with only their eyes showing anyways, so a burglar could easily blend into a crowd. He also could get away without anyone being able to identify his vehicle because it would be probably be covered with snow, sand from the roads, and slush. His license plate would be covered up by the miniature snowdrifts that build up on anything that isn't completely smooth, making a positive ID practically impossible. Unless he's like that one crook I heard of on the radio the other day. He was very careful all the way through the burglary, but made one little mistake as he left. He backed into a snow bank to pull out and left a perfect imprint of his license plate in the snow, leading police straight to his door. Oops.
Occasional frostbite is nothing to get excited over. Don't try telling other Minnesotans that the tip of your pinkie got frostbitten while you were out shoveling 2 feet of snow and expect them to be impressed. It happens and it's no big deal.
When schools close for a snow day during a blizzard, it generally doesn't deter people from going anywhere. So the kids have a snow day? Load 'em up in the car and let's go shopping!
During the summer, Minnesotans talk about the road construction. During the winter, they talk about the weather. When it hits 20 below 0, Minnesotans start using the phrase, "Cold 'nuff fer ya?" liberally. At that point, most will also start wearing a knit hat outdoors as well.
