Trip from SW OK to Milford, MI

Okay we stayed at camp Dearborn. We had full hookup, we camped from Wednesday to Monday. Filled up a little on the weekend. I'm sure during the summer it gets pretty busy with family and kids it's a camp. For us it worked out fine. We were close to relatives in Milford. Sites were nice not on top of neighbors. Pretty with all the trees starting to change color. We then stayed at Harrisville State Park right on Lake Huron. It was real nice. Now we are in Petosky at Magnus Park. We have a great view of Lake Michigan nice bike path or walking.

Next I'm looking for a place for one or two nights sw Michigan. Then a place for Illinois or Iowa heading to Omaha, NE. Can anyone suggest any sighting places that might be of interest. Thks
