I love driving around the Midwest and in the plains in the States. If you get away from the large 4 lane highways, there's all kinds of stuff.
I found a strawberry festival and ate enough strawberry things to make myself sick. I found an artists commune and stayed with those weird old hippies for two days..I found a diner with a waitress who was in her 90's and had worked the same job for like 70 years.
We happily spend our vacations just driving around in the middle of the country with no plan.
Drive side roads.
