<p>I can’t answer the 2nd question since I am not a ND student, but I originally lived in Indiana and now live in the Southwest (so the opposite of you two). And I guess I could ask you a similar question. How do you survive the scorching hot summer? You just get used to it over time. Your blood will thicken and you will start to love the beautiful Hoosier winters. And as with all places, the weather doesn’t just suddenly drop 50 degrees. It is a gradual decline. And yes, you can wear jeans or sweatpants. And look at it this way, when the stores start to sell winter clothes, you can actually buy them and wear them throughout the season instead of just on one or two days!</p>
