We also went to Sioux Falls SD. I really liked this town and wished we had more time there. We also travelled in to Iowa so that I could see some of the area where my greatgrandfather and his cousins came from . At one rest stop they had a neat display about quilt blocks which is really let me read about the underground railroad in that state.
We crossed a few well known rivers that I have read about and that was neat to see how wide and dirty they were. You can see the affects of industry on the environment in the rivers.
Driving through Michigan, while it is a pretty state, it certainly needs some road work done big time. Not good to travel when you are desperate for a bathroom break that's for sure. Our trip went really smoothly until we got to Michigan by the way. Cause there was a bit of road work changing our route, we found ourselves venturing down new paths and having a bit of a marital dispute as the husband said we should go one way and the driver glimpsing a sign amongst the foliage would take us another. But we worked through it. But I don't think that we will be returning soon. Sorry Michigan. It was just a bit too much.
