Unquestionably, Minnesota is known for its winters. Yes, they are very cold. We take pride in our toughness to deal with the winters, but honestly, they're a pain for us too. The trick is to bundle up, keep your head down, and move quickly.
Spring in Minnesota is wet and cold. But that doesn't keep us from breaking out the short pants if the temperature rises above a balmy 50 degrees. Spring is a hopeful time, when people emerge from their caves and take to the trails.
Summer in Minnesota: if you simply compared the numbers of people you see to winter, you'd think the population grew 100 fold. Beautiful weather, incredible parks and trails, and people dying to get outside combine to create a friendly, cheerful community in the summer in Minnesota.
