During September of this year I’ll be driving from NC to Hoosier National Forest and on to Wall, SD and be passing through Iowa and Minnesota on the path shown below. These two states don’t seem to have a NF where I would prefer to camp the night. I know that I could likely find truck stops or WM’s to spend the nights but would rather stay at a campsite even if I needed to pay a bit for it. If any of you have tips for a few sites between, say, Iowa City and Sioux Falls that you could recommend I’d sure appreciate it. Many thanks!
