Yup, the US is huuuuuge. No matter how long your vacation is (assuming it's under 2 months), I'd stick to a single section of the states and see as much as you can. I've been traveling the US since I was 5 (for 22 years now), and there's still a lot I haven't seen!
Yeah, Minnesota, not so much, especially if it's winter. But, if you're not looking to see famous things and it's spring or summer, Minnesota is great. We have beautiful forests and lakes, lots of good camping, and a nice metro area. We don't get a lot of foreign tourists though, so you'll probably get stared at with your accent

But personally, if I could only visit a part of the US, I wouldn't chose minnesota
