I’ve been to Wisconsin and Minnesota, Illinois, Indiana, Ohio, Tennessee, Kentucky, Virginia, Pennsylvania, ..well, lots of states with the same types of topogragraphy.
Though I find it all very beautiful and diverse (and often surprising) the climate of the Midwest is not good for me, so I only visit. And admire the people who like the snow well enough to stay!
And I know what you mean about a “whole thread.” The West is like that.
I was nineteen when I took my longest-yet driving excursion: Michigan to DC; DC to Los Angeles, taking a north-central route, then LA back to MI on a south-central route. Most of what I saw was absolutely amazing. Unfortunately, I had time constraints. I needed to be in LA for a christening, so I did the DC to LA leg in just three days. Then, I had to be back in MI for school, so the trip home was four days long.
I can't wait until my kids are a bit older. I want to make an entire summer out of it. For now, we're all content to keep discovering parts of Michigan we've never seen before.
