Kids want to head to the Great Lakes area. We will be heading out from Oklahoma, late summer. Can go any number of ways. Straight North up through Kansas, Iowa, Wisconsin, or could go through St. Louis, Chicago way, or even head to Tennessee area then up. Obviously this could be some kind of loop as well. Don’t have to come back the same way we go. Just looking for fun things to see or do on the way and even for suggestions up around Mackinaw City or Sault St. Marie area.
