We stayed in Rockford IL which is the home of the real Rockford Peaches, the women’s baseball team from WWII era..
The RV P all we stayed at is the Blackhawk Valley Campground. It’s huge with large sites and lots of green open area. It’s also right on the Kishaaukee River, several seasonal sites are along the river and there’s a small beach.
Here is a picture of the view from our front door:
